Ternary Blended Concrete

A major problem in cement manufacturing is the increased emission of CO2. About 5% of worldwide man-made emission of CO2 is generated. Cement being the predominant material of concrete, the usage needs to be reduced by using admixtures or SCMs to replace partially, the percentage of OPC in concrete. Admixtures like Metakaolin (MK) and Waste Glass Powder (GP) were used to replace OPC, producing a ternary blended concrete. The cement replacement with GP is from 5% to 45% and MK is from 45% to 5% both in steps of 5% and hence a total of ten combinations including control mixture (100% cement) were studied for M30 grade. Mechanical properties are evaluated by conducting compressive, split tensile strength tests. The initial compressive strength of mix containing 20% GP and 30% MK with 50% OPC, after 7 days curing is found to be higher by 5%, compared with control mix.

Ternary Blended Concrete

The sum of CO2 that has been released into the atmosphere is roughly equal to the amount of cement produced. Cement manufacturing now consumes many natural resources and cement substitute materials in the analysis of Micro Structural Properties of Ternary Blended Concrete. The mixed proportion in this analysis is made of M30 Concrete. The cement is substituted with a mixture of two materials in amounts ranging from 10% to 50%. For the mix of materials, Fly Ash is kept constant. The specimen is a 150mmx150mmx150mm cube, and the concrete is cast in a 150mmx300mm cylinder. The cast specimens are held for 28 days to cure. Compressive and split tensile strength tests are used to achieve the results. The combination at 10%, at 20%, at 20%, and 20% produced better strength results in all proportions from 10% to 50%. Besides, scanning electron microscopy techniques were used to understand better phase changes and the formation of microstructures to maturing the combination of materials at various percentages. SEM was used to evaluate the microstructure of the concrete for five different varieties, which helps with solid growth. With the highest compressive strength gained among all the mixes from 10% to 50% with combinations for M30 grade of concrete at 28 days, significant innovative information on particle shape and microstructure was observed. Via SEM study, a good correlation of this Microscopical quantitative knowledge and material properties is also presented.

Self Compact Concrete

In this work, waste glass powder from broken windows and plastic fibers from waste polyethylene terephthalate bottles are utilized to produce an economical self-compact concrete. Fresh properties (slump flow diameter, slump Flow T50, V. Funnel, L–Box), mechanical properties (Compressive strength and Flexural strength) and impact resistance of self-compact concrete are investigated. 15% waste glass powder as a partial replacement of cement with five percentages of polyethylene terephthalate plastic waste were adopted: 0% (reference), 0.5%, 0.75%, 1%, 1.25% and 1.5% by volume. It seems that the flow ability of self-compact concrete decreases with the increasing of the amount of plastic fibers. The compressive strength was increased slightly with plastic fiber content up to (0.75%), about 4.6% For more than (0.75%) plastic fiber. The compressive strength began to decrease about 15.2%. The results showed an improvement in flexural strength and an impact on the resistance in all tested specimens’ content of the plastic fibers, especially at (1.5%) fibers.

Concrete is the abundant man made material in the world. The quantity of Co2 emission through the industrialized of OPC is almost one ton. The Co2 emission is approximately 7% of the worlds Co2 emission. In order to decrease the Co2 emission and create the sustainable environment we have to develop greener building material. In this the TiO2and GGBS is use in cement on mixing of concrete. In this TiO2 go about as a self cleaning material and the solid with expansion of TiO2 is 1% by mass of the concrete dependent on the past tasks are finished by the scientists and GGBS with 5%, 10% and 15% by mass of cement was prepared. In this research hardened tests are Compressive, Flexural, Split Tensile strength tests of concrete observations mixed with TiO2 and GGBS for optimum content was considered
