Industrial waste productions are increased these days, which is causing grief to the environment. Hence it is necessary to cut down the waste generation or reuse the waste. It is needed to utilize the waste to reduce environment damage. It is known that ashes produced from the industries can be used in construction. Ashes like fly ash can successfully replaces the cement showing good results. Researchers are finding the new ways to use ashes in production of cement. Now a days cement manufactures adulterates the cement with pozzolanic material like fly ash, rice husk ash, sugarcane bagasse ash etc. Using these product in concrete, they not only reduces the pollution but also lower the price effectively. If these fillers added in proportion it enhances the properties of concrete like workability, strength, water absorption, permeability etc. considerably. This review paper represents the properties of concrete when cement gets partially replaced by sugarcane bagasse ash, fly ash and rice husk ash. This paper primarily concentrates on the properties like durability and strength when cement concrete contain fillers in it. It also considers the non-destructive tests which are performed.

Chapter 3 is based on performance of mortar grouts incorporating rice husk ash (RHA) and fly ash (FA). Detailed experimental work was conducted to investigate the mechanical properties of mortar grout using RHA and FA as partial replacement of cement. This study investigated the compressive strength and durability of mortar grouts in their hardened state. Durability tests such as water absorption, apparent volume of permeable voids, sorptivity, and rapid chloride penetration tests are researched. Detailed results and discussion which focused on mechanical properties as well as durability of hardened state mortar grout are presented. It was confirmed that the inclusion of blended RHA and FA significantly improved the compressive strength of mortar grouts. The durability of mortar grout increased along with a longer curing time. Hence, RHA and FA can partially replace cement in the production of mortar grouts.

Concrete is an essential material in all constructions throughout the world. It has lot of uses in our daily routine life. Every material has to deteriorate and damage due to many factors in the same way the concrete also deteriorates. The carbonation process is identified as a main reason for the corrosion in reinforcement concrete structure. The mechanism of carbonation which includes the entrance of carbon dioxide (CO2) into the solid permeable framework of concrete to shape a situation by decreasing the pH around the fortification and inception of the corrosion procedure. This paper investigates the impact of the carbonation on the characteristics of the concrete like strength in compression, split tensile strength, flexural strength, shear strength and durability. The addition of supplementary cementitious materials like fly ash, GGBFS, rice husk ash, metakaolin is known to enhance the strength and durability of concrete in construction. In this paper an accelerated carbonation test has been done to assess concrete carbonation on specimens made with cement and with the partial replacement of cement by fly ash GGBFS, rice husk ash, metakaolin. An accelerated carbonation chamber has been constructed for creating an environment of carbonation process to occur and also the passage of carbon dioxide gas is kept constant for all the cubes, cylinders and beams. Concrete cubes, cylinders and beams are prepared for M30 grade subjected to different percentages of carbonation.
