Portland cement as ingredient in concrete is one of the fundamental development materials generally utilized particularly in creating nations. The expanding interest for concrete is relied upon to be met by fractional bond substitution. The look for elective fastener or concrete substitution materials prompted the disclosure of possibilities of utilizing modern side effects and farming squanders as cementitious materials. A portion of the waste items which have pozzolanic properties and which have been considered for use in mixed bonds incorporate wood fiery debris, fly powder, Silica smolder, Volcanic cinder, copper slag, quarry dust, Rice husk cinder . It is a waste material coming about because of the mechanical processing or preparing of timber into different shapes and sizes. The issues of profitability, economy, quality and condition, they need to rival other development materials. In this investigation three sorts of squanders materials wood ash, sugar cane bagase ash and rice husk ash and ordinary aggregate were utilized for preparing cube specimens. There are M25 grade of blended extent are use. Squander materials are use in concrete with the substitution bond of 4 , 8 , 12 and 16 . These beams, cylinder and cube are tries on 7, 14, and 28 days. The compressive quality, flexural quality, and tensile strength are determined with the help of UTM and CTM machine.

The prime objective of the study was to evaluate the structural properties and potential of concrete containing coal fly ash that of concrete containing no coal fly ash of corresponding mix proportions and strength. The cubes were tested for the compressive strength and beams specimens were tested for flexural strength. Splitting tensile strength tests were conducted on cylinder specimens. The total numbers of 60 cubes, 40 beams specimens and 40 numbers of cylinders were tested for compressive strength, flexural strength and splitting tensile strength respectively at different ages to study the following aspect. The effect on unit weight of concrete after incorporating varying proportions of bottom ash. The effect of coal fly ash on workability C.F of fresh concrete. The effect on compressive, flexural and splitting tensile strength using bottom ash in varying percentages as a partial replacement of fine aggregates. Mix containing 30 and 40 bottom ash, at 90 days, attains the compressive strength equivalent to 109.13 and 105.17 of compressive strength of normal concrete at 28 days and attains flexural strength in the range of 112 116.3 at 90 days of flexural strength of normal concrete at 28 days.

This Experimental work shows the investigation on M30 grade due to incorporation of glass fibers. In this Experiment, we used the glass fibers of Filament diameter 14 microns with aspect ratio 857.1 at various percentages as 0 , 0.4 , 0.8 , 1.2 , 1.6 by the weight of cement on M30 grade of mix proportion 1 1.60 2.96 with water cement ratio 0.45. Hence, in this research the Experimental investigations and analysis of results were conducted to study the compressive, tensile and flexural behavior of composite concrete with varying percentage of such fibers added to it. The concrete mix adopted were M30 with varying percentage of fibers ranging from 0, 0.4, 0.8, 1.2 and 1.6 by weight of cement. On the analysis of test results, the concrete with straight glass fibers had improved performance as compared to the conventional concrete, which was readily available in market. From the experimental investigation, It has been found that optimum dosage amount of glass fiber of concrete is 1.2 by weight of concrete because at this point the compressive strength of GFRC increased up to 17.36 as compared to plain concrete while the flexural Strength increased up to 35 and Split Tensile Strength increased up to 40. The common person in their regular constructions could easily adopt these sustainable improvements or modifications.

In today's modernization of technological field lot of studies and trials are being carried out for manufacturing an excessive strong, long lasting and heavy duty concrete. In this study how the silica fume and steel fibers are beneficial if added to normal concrete is discussed. The results of this study depicts that the addition of silica fume and steel fibers in the normal concrete enhance the concrete properties like workability, brittleness, bond strength, corrosion resistance, fire resistance, acid resistance and ultimately increased durability of the structure which can be achieved by adding the appropriate quantity of silica fume and steel fibers. Lot of fact finding experimental examination and there analysis were carried out for fining out the compressive, split tensile and flexural behavior of composite concrete with adding different proportion of silica fume and steel fibers. The concrete mix used for this study was M30 and the addition of silica fume and stainless steel fibers was experimented with different proportions like 0 , 4 , 8 , 12 and 16 and 0 , 0.5 , 1.0 , 1.5 and 2.0 respectively. The steel fibers used in this study were of .50 mm diameter and 40 mm in length as a partial replacement of cement weight. The result after analyzing showed that when the normal concrete is mixed with silica fume and straight steel fibers in proper proportions it improves the properties and execution of composite mixture as compared to the ordinary concrete. This rational advancement can be positively accepted and utilized in the regular constructions.

Concrete is the most extensively used construction material in the world, which consumes natural resources like lime, aggregates and water. The worldwide production of cement has greatly increased, due to this production environmental pollution increases with emission of CO2 gas. To reduce this effect cement was replaced by some supplementary materials like Metakaolin, Fly ash, Bottom Ash, Ground Granulated Blast Furnace Slag GGBS and Rice Husk etc.. In this content Metakaolin was a pozzolanic material used in wide range in replacement of cement. Metakaolin is dehydroxylated aluminum silicate, due to its pozzolanic activity the strength properties and durability properties of concrete increases and reduction in Porosity and Permeability also. Now a day's availability of natural sand is constraint, so alternative material called ROBO Sand having similar properties as that Natural Sand is used in place of Natural sand to study the fresh and hardened properties of concrete. In this present investigation cement is replaced partially with metakaolin in varying percentage i.e. 0 , 6 , 12 , 18 and 24 and natural sand with 45 ROBO sand to get the different concrete mixes. The fresh and mechanical properties of concrete i.e. workability slump test and compressive strength, split tensile strength and flexural strength at 7 days, 28 days and 56 days are studied of the different concrete mixes and results are compared with conventional concrete.

In this paper the properties of conventional concrete have been developed. Conventional concrete has the property of high brittleness and less flexural strength. This is a undesirable characteristics is mother of development of Flexible concrete to improve this deficiency. The Polyurethane fiber has the ability to impart considerably flexibility in concrete. For this purpose concrete cube, cylinders and beams experimentally tested. By the mixture of traditional concrete ingredients and special polyurethane fibers addition with water super plasticizers for good workability purpose. The test results have proved to be increased flexibility of the concrete.

Self-compacting concrete (SCC) is relatively a recent development in the construction world. SCC is defined basically by two properties: Deformability and segregation resistance. It flows under its own weight while remaining homogeneous in composition. This research is aimed at examining the feasibility of using Rice Husk Ash as supplementary cementations material. In this research, the main variables are the proportion of rice husk ash (0%, 10%, 15%, 20%) and cement content.All the results were in range as per code specified. Mix 20RHA showed minimum workability.. The increase of about 25% strength at 7 days, 33% strength at 28days and 36% strength at 56 days were observed with increase of RHA content from control mix (0RHA) to 15RHA. Maximum splitting tensile strength was also obtained bythe mix 15RHA. Greatest increase in mechanical properties was observed for the mix containing 15% rice husk ash. The inclusion of rice husk ash as replacement of cement does not affect the strength properties negatively as the strength remains within limits up to 20%replacement. Inclusion of RHA showed great improvement in durability Properties of concrete.
