| contents | The use of concrete increasing annually due its favorable properties and readily availability. When the concrete exposed to environment it starts to disintegrate due to chemical attack. The majority of chemical attacks on concrete are in the form of a reaction between aggressive agents and the cement matrix, although reactions can also happen with the aggregate. However, the use of Portland cement concrete has an impact on the environmental due to the emission of CO2 in the atmosphere. On the other side handling of plastic waste was a major problem all over the world. So, to solve these problems the investigation had been established as the use of rice husk ash and silica fume as partial replacement of Portland cement to increase strength at early and later age and exhibit considerable enhancement in durability due to its micro structure thereby reducing the permeability of concrete, also the plastic waste (LDPE) obtained from industry was used as a replacement for fine aggregate. From the literature study the addition of 20% of RHA and 10% SF, gave a better strength, and the addition of plastic waste in the proportion of 5, 10, 15 and 20%, plastic waste decreases the compressive strength the addition of RHA and SF compensate those losses. The concrete is casted at different mix proportion of with and without LDPE waste so as to compare the strength. With the addition of additives at different ratios, the different specimen of concrete cubes was casted and the optimum mix strength of concrete specimen (compression) was checked, for the optimum mix, the performance over the durability was carried (magnesium sulphate, sodium sulphate and sulphuric acid) under the ASTM standards. To analyze the deterioration and homogeneity of concrete cement paste SEM analysis is carried. At final, the of the ordinary Portland cement concrete and the concrete made with different additives. |
