Recycled aggregate (RA), the environmental rate is low due to insufficient strength and also to ensure that high porosity of the concrete. From the literatures lot of researches to investigated the presence of this recycled aggregate. To overcome this problem using weld slag form the material manufacturing industry, improve their strength of recycled aggregate mixed with (0-100 %) replacement. To avoid the wastages of copper weld slag material and increasing their strength, it is destroyed with a powder shaped material. This investigation replaces with 0%, 10%, 20%, 30% recycled aggregate and cement with weld slag. And tensile strength, compressive strength, flexural test were carried out by the universal testing machine

Increasing wastages leads to land disposal related to the social issues, accumulated to their huge amount of land filling elements. In general cement is an artificial resources, normally fine grain structure and mixed al the chemical content and water conformal characteristics. But this artificial material some effect of causes to the environmental effects such green house effects. Recent researchers work with lot of various industrial wastes and reuse materials. Similarly wood ash is an essential part of this concrete. This paper investigates the effect of wood ash to the tensile, compressive, and flexural tests explained in detail. The wood ash content mixed with addition of 0%, 15%, 25 % and 35% respectively remaining cement enhanced. This proportions of wood ash admixtures with the concrete M35 grade.

Resources are found to be depleted due to making of ordinary concrete. One of the main ingredients in making concrete is fine aggregate. There is a huge demand for fine aggregate at present scenario. As growth of industries takes place, production of slag from industries increases In this work an attempt has been made to use fluorescent lamp powder 20% replacement of cement. And the fine aggregate was fully replaced by iron slag and quarry dust. The fine aggregate replaced by iron slag 50% and Quarry dust 50%.

The large quantity of concrete is used by the construction industry all over the world, probably second largest after water. In India, the conventional concrete is produced by using natural sand as fine aggregate that are available from riverbeds. But diminishing sand resources poses the environmental problem and hence government restrictions on sand quarrying resulted in scarcity and significant increase in its cost.

A mixture of cement, fine aggregate, coarse aggregate is known as concrete. It plays an important role in infrastructure development like buildings, bridges and industrial structures etc. Long term performance of buildings without disintegration helps economies of nation. High performance concrete (HPC) is a concrete which shows special performance than normal concrete. This leads to usage of admixtures to improve concrete performance

Self-curing concrete is provided to absorb water from atmosphere from air to achieve better hydration of cement in concrete. It helps to solve the problem that the degree of cement hydration is lowered due to without curing or improper curing, and unsatisfactory properties of concrete. According to the previous research works, high performance self-curing agent about 0.1 – 5 % of cement weight of the concrete is added to the concrete during mixing. The self-curing agent can absorb moisture from atmosphere and then release it to concrete.
