This can be up to 45% from my research. INTRODUCTION Concrete's versatility, durability, and economy have made it the world's most useful construction material. So, after you have burned your supply of wood or leaves, now let it cool. In general, the use of wood ash in RCC reduced its 28-day compressive strength, especially when the wood ash was used to replace the cement (#28 to #30). Om Suganya, is an Assistant Professor (SG), working in the School of Mechanical and Building Sciences, VIT University, Vellore. Calcium is in higher concentration in the bark and leaves of a tree. Conclusions - "Strength development in concrete with wood ash blended cement and use of soft computing models to predict strength … The 28-day flexural strength of beam for all the three percentages of cement with wood ash was found to be satisfactory. Another benefi-cial application is to use the wood ash as a cement replacement, a mineral admixture, or an aggregate filler in concrete. My current theory: The main component of wood ash consists of calcium in some form (e.g. Wood ash is commonly disposed of in landfills, but with rising disposal costs, ecologically friendly alternatives, such as serving as compost for agricultural and forestry applications, are becoming more popular. The optimum replacement of cement by wood ash is therefore 20%. wood ash varies from 4% to 70% in wood ash that makes it a potential substitute in cement industry either in production or in application stage. This marginal difference tends to decrease with prolonged curing durations, especially beyond 28 days. Cement Also using a new statistical theory of the Support Vector Machine (SVM), strength parameters were predicted by developing a suitable model and as a result, the application of soft computing in structural engineering has been successfully presented in this research paper. structural concrete and concluded that the wood ash increased the water demand and reduced the mechanical strength of concrete; while there were insignificant effects on the durability and a noticeable reduction in the dry shrinkage.

Wood ash (WA) is the residue generated during incineration of wood and wood products. Wood ash, fly ash, and recycled aggregate concretes are the alternative concrete types discussed in this study. Modern brick manufacturers generally use Portland cement as a stabilizer, but one effective stabilizer that has been around throughout history is wood ash. Fly ash can replace Portland cement up to 30% without losing significant compressive strength of the concrete. Just mixing Wood Ash into Portland is certainly good - but to replace Portland all together with wood ash requires that the ash be heated to red-glow, then cooled as rapidly as possible. The saw dust has been acquired from a wood polishing unit. Fig. MATERIALS AND METHODS A. [2]-[5] studied the effects of wood ash on the fresh and hardened proper-ties of flowable fill and concluded that the wood ash could be successfully used in flowable fill. The decrement in strength parameters can be due as the wood ash content increase, the amount of cement needed to coat the filler particle increase leading to poor bonding in the matrix. Wood ash is the residue produced from the incineration of wood and its products (chips, saw dust, bark) for power generation or other uses. cement without adversely affecting the strength properties of concrete within certain limits. These ashes are discarded and dumped here and there, resulting in pollution of the environment. Wood ash is an admixture: a pozzolana. WWA can be a cement replacement once its composition is monitored. Using the ash with the high LoI resulted in significantly lower compressive strength compared to the other two ashes. The compressive strength and water absorption properties of the samples were determined for all mix proportions. In case of M30 it can be seen that the strength attained at the age of 56days by both type of cubes is same. Basha et al. 2 presents the strength parameters (compressive, split tensile strength and flexural strength) at 28 days for water to binder ratio of 0.4. When the ash is mixed with water, the soluble component of wood ash (10% pot ash) dissolves into the water. concrete, percentage increase of wood ash showed increase in strength. 2. strength gain of fly ash concrete exceeds that of conventional concrete, enabling equivalence at the desired age. 2 Strength parameters at 28 days for 0.4 waterbinder ratio. She is pursuing her Ph.d. (VIT University) in high strength concrete using nanomaterials. Leave only the mushy sloppy ash. This was attributed to the increased pozzolanic activity. reacts vigorously with sulfate and has devastating effect on concrete life. It was concluded that nanosilica enhanced workability and improved both early and later strength development in wood ash concrete with 1.5% as the optimum addition. Concrete with no wood ash and nanosilica served as the control. Regardless of replacing cement or sand with WAs, the compressive strength decreased compared to a reference without ash, however, the decrease was small for two of the ashes. DOI: 10.1016/j.jare.2014.08.006 Corpus ID: 16989378. The maximum strength was obtained for 3% replacement which is 29.7N/mm 2 . So get a huge pile of leaves and or bark or the actual wood and burn it. Average Cement Consumption from 2003 2016 4.4 Wood Ash Demand and Supply Analysis T he woo d ash percentage obtained from 3.1 was used to calculate the wood ash requirement for use in low strength concrete. [...] Key Method The strength parameters (compressive strength, split tensile strength and flexural strength) of concrete with blended WA cement are evaluated and studied. It is observed in Bangladesh that there is an extensive use of wood as a solid biomass for heat and electricity production, which led to increase in the amount of combustion residues known as ash. When wood ash was added to concrete, the compressive strength of concrete was found to reduce marginally with respect to the reference mix and the optimal value of compressive strength was obtained at 5% replacement. The strength parameters are compressive strength, split tensile strength of concrete with wood ash cement are studied. Wood ash can be used as partial replacement of cement in concrete to increase the strength and thermal insulation for cement blocks. In this research, wood waste (sawdust and wood shaving) ash (WWA) of pretreated timber of 0, 5, 10, 15, 20, 25, and 30% by weight of cement was added as a supplement to a concrete of mix proportion 1:2:4:0.56 (cement:sand:coarse aggregate:water cement ratio), and the strengths and the water absorption of the matrix were evaluated. The strength parameters (compressive strength, split tensile strength and flexural strength) of concrete with blended WA cement are evaluated and studied. Wood ash is generated as a by-product of combustion in wood-fired power plants, paper mills, and other wood burning industries.

Wood waste powder replacement with sand for 10%, 20%, 30% was found to be higher than conventional concrete .Using of wood waste powder as replacement of sand is cost effective and user friendly. Use enough so that the ash is completely covered then add a little bit more. The aspects of wood ash such as its physical, chemical, mineralogical and elemental characteristics as well as the influence of wood ash on properties such as workability, water absorption, compressive strength, flexural rigidity test, split tensile test, bulk density, chloride permeability, freeze thaw and acid resistance of concrete have been discussed in detail. Wood ash, as a replacement for cement in soil treatment, seems to be a promising material. 7: Modulus of Rupture. Widely used in the UK to increase the strength of concrete, fly ash is also used to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product. Strength development in concrete with wood ash blended cement and use of soft computing models to predict strength parameters. Keywords: Wood ash, concrete, strength, cement replacement 1. Once the ash is well mixed allow it to sit for a minute then pour off all excess water. The XRD test results and chemical analysis of WA showed that it contains amorphous silica and thus can be used as cement replacing material. Wood ash (WA) is the residue obtained from combustion of wood and its products by burning it with an average temperature of 700 o C in open field. Wood-cement-ash particleboards (WCAP) were made with 10%, 20%, 30%, 40%, and 50% of wood ash as a partial replacement for cement with wood particles and tested for bending strength, stiffness, water absorption, and thermal properties. Fig. Portland cement is a relatively expansive ingredient in concrete, and comprises of 10 to 20 percent of concrete's weight. In this study, Wood Ash is studied its workability and strength as partial cement replacement in conventional concrete. strength of 16.7N/mm2.The 28 day compressive strength of cube with 8% of cement replacement is only 24.74N/mm2 which is lesser than 25.8N/mm 2 .Therefore, it is observed that the cement can be safely replaced with wood ash up to 5%. Workability and compressive strength of the plain and composite concrete were determined. Mihir Mishra, is currently in his third year, pursuing a Bachelor’s degree in Civil Engineering from VIT University, Vellore. It could be managed by using wood ash as a stabilizer of soft clay. concrete cubes measuring 150mm x 150mm x 150mm were made from five different concrete mixes prepared by using IWWA to replace 0%, 5%, 10%, 15% and 20% of Portland cement by mass. water needed to be added and the results depended on the water:cement ratio rather than the ash mass. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials. He has published 2 papers in peer reviewed international journals in the field of structural engineering.
