It is shown that some of the wastes have properties that would improve the quality of concrete produced. One such waste is agricultural waste rice husk, which constitutes about one-fifth of 600 million tones of rice produced annually in the world. The performance of RHA concrete was found to be varied among those of researchers and most of the studies encompassed for the utilisation of high grade concrete. This paper reported the investigation carried out on the mechanical properties of normal strength concrete of grade 30 N/mm2 with various partial replacement level of ordinary Portland cement (OPC) with Rice Husk Ash (RHA). Two(2) batches of same grade of concrete with and without use of superplasticiser (Sp) were adopted. The mechanical properties evaluated are in terms of compressive strength, flexural strength and tensile splitting strength of RHA concrete with and without superplasticiser (Sp). The results show that the optimum replacement level of RHA was 20 % and with the addition of Sp the replacement of RHA was taken as 40 %. However, the results of the study show that the performance in term of flexural strength and tensile splitting strength does not significantly improved with the replacement of cement with RHA.

Bagasse ash (BA), the residue obtained after the burning of sugarcane bagasse as a fuel, has pozzolanic properties with potential use as a supplementary binding material (SCM). Use of Bagasse ash (BA) as a mineral admixture needs to be established, especially in India, where sugarcane cultivation is widespread, to reduce land required for its disposal and cement consumption in construction industry. Hence, to encourage commercial use ofBA with minimum processing, an evaluation of the physical, chemical and  morphological characteristics of a locally available BA and its effect, as SCM on properties of structural concrete was taken up.This research work describes the feasibility of using the Fly Ash (FA) Rice Husk Ash (RHA) and Sugarcane Bagasse Ash(SCBA) waste in concrete production as a partial replacement of cement. This present work deals with the effect on strength and mechanical properties of concrete using Triple blending of cement concrete using FA, RHA and SCBA instead of cement. The cement has been replaced by rice husk ash, accordingly in the range with 0%, 10%, 20% and 30% by weight. Concrete mixture of M20 and M25 and M30, were produced, tested and compared in terms of compressive strengths with the Conventional concrete. These tests were carried out to evaluate the mechanical properties for the test results of7, 14, 28, 56 and 90 days for Compressive strengths and Tensile & Flexural Strengths at 28 days. The durability aspect of the samples for Acid attack, Alkaline attack and Sulphate attack was also tested. The result indicates that the FA, RHA and SCBA improve the Compressive Strength and durability of concrete.  


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.

Rice husk ash (RHA) is an agricultural based pozzolanic material, which contains high amount of silica content. This experimental research was conducted on Self Compaction Concrete (SCC), to generate an economical concrete by using Manufactured Sand (M-sand) and Rice Husk Ash. Natural River sand usage is damaging the river beds, causing the drastic changes in ground water table and cost of river sand increasing day by day. To overcome this problems manufactured sand is used in SCC production. Rice husk Ash is very cheaper when compared to the Cement. It is extracted from Rice Husk which is a waste of Agricultural product. This material can be useful to generate a sustainable construction material. This paper presents the experimental results on development of mechanical properties of SCC with M-sand and Rice Husk Ash. Experiment conducted on 6 different mixes. i.e Partial Replacement with RHA (0%, 5%, 10%, 15%, 20%, 25%). For each mix Fresh properties (Slump flow & L-Box Test) & mechanical properties (Compressive strength, Split Tensile strength and Flexural strength) for 7days, 28days and 60days along with Density comparisons are compared.
