Strength Properties of Concrete Specimens with Metakaolin and Methylcellulose

Merin Clara Mathan | Cinaya Tony

Abstract: Concrete is the most commonly used material for construction. Production of cement results in a lot of environmental pollution as it involves the emission of CO2 gas. Supplementary cementatious materials including silica fumes, fly ash, slag, Rice Husk Ash and Metakaolin have been used in recent years as cement replacement material for developing HSC with improved workability, strength and durability with reduced permeability. Metakaolin is a dehydroxylated aluminium silicate. It is an amorphous non crystallized material, constituted of lamellar particles. From the recent research works using Metakaolin, it is evident that it is a very effective pozzolanic material and it effectively enhances the strength parameters of concrete. Reducing sulphate attack and improving air-void network. Methylcellulose (MC) will be the one of the bonding strength increasing material used to increase the strength of the concrete along with the metakaolin. In this thesis paper, studies on partial replacement of cement with metakaolin as different percentage in M30 mix. The replacement levels were 10 %, 15 %, 20 %, 25 %, upto 30 % (by weight) for Metakaolin. The result obtained from the test is compared with normal specimens without replacement. At some percentage there will be the decrease in strength. At some percentage there will be the decrease in strength. To increases the strength in that percentage MC will be added and compare with the control specimen.
