· • Reclaimed concrete can be used in walkways providing a walkable surface and at the same time providing gaps for rain water to reach the soil. By doing this the amount of runoff water will also be reduced, resulting in a smaller storm sewer system. • Old concrete can be recycled and turn into aggregates after it has been crushed and processed.
1. Introduction. Concrete is the most widely used building material, and its demand continues to increase with the advancement of global infrastructure construction,,, .It is reported that the production of cement concrete around the world is estimated to rise to 18 billion tons by the year 2050,, .At present, readymixed concrete is undoubtedly a substantial part of concrete .
construction of deep underground repositories for disposal of radioactive waste. One purpose they serve is to fluidise fresh concrete at very low water/cement ratios enabling the production of high performance concrete. Although they are added only at the order of 12% of dry cement, their total mass in a repository is considerable. Radionuclides
· T3 – treatment of waste metals and metal alloys by heating for the purposes of removing grease; T7 – treatment of waste bricks, tiles and concrete by crushing, grinding or reducing in size;
· Several research studies have been conducted on the suitability of the use of cockle seashell waste as additive material to concrete. The primary advantage of using the marine cockle seashells as partial replacement of cement in concrete preparation is the significant reduction of environmental pollution. The incorporation of seashells in concrete can put waste .

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of manufacture are .
· Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates.
