material such as sand, gravel, crushed stone, blastfurnace slag, and lightweight aggregates that usually occupies approximately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete.
The use of crushed granite fine to partially replace Makurdi river sand in concrete production will require a higher water to cement ratio, when compared with values obtained with the use of only Makurdi river sand. 2.
Crushed concrete aggregate (CCA) is made from unused, returned concrete, and old demolished concrete that is clean enough to be used for new concrete mixes. Crushing old concrete to make aggregate for new concrete is growing in popularity for many reasons the with first being able to create a more sustainable or "green" concrete.

In this direction, an experimental investigation of
Fig. 2(a) and (b) illustrate the effect of the percentage of glass as aggregate replacement on the initial and final setting times of concrete mixes made with the considered types of concrete mixes. Both initial and final setting times exhibit an increasing almostlinear relation with the percentages of replacement with fine glass and with coarse glass in concrete made with FWG and CWG.

Nofines concrete. This form of lightweight concrete is generally a crushed rock or gravel of 20 mm single size aggregate (10/20) coated in a cement slurry with no fine aggregate addition. Strength is between 5 and 15 N/mm 2 at 28 days. It has good drainage properties due to its open texture.
aggregate concrete by partial replacement of natural stone aggregate by brick aggregate and it was found that upto 15% replacement there is no reduction of strength. Debieb and Kenai  showed that it is possible to produce concrete containing crushed bricks (coarse and fine) with characteristics similar to those of natural aggregate concrete
The reuse of crushed waste ceramic tiles as a substitute for fine aggregate in concrete has been investigated in this study. Waste ceramic tiles obtained from building demolition sites and leftovers from new building sites were used. The crushed waste ceramic tiles were substituted in place of fine aggregates in the following percentages (0%, 20%, 25%, 30% 35% and 40%) in the concrete mix.
The mixes of each series incorporated different percentages of very fine sand (VFS) as a replacement for fine aggregate. Results indie that the water demand increases rapidly when the VFS replacement is more than 5 percent in natural sand concrete and more than 15 percent in crushed stone sand concrete.
New type of crushed sand to replace natural sand in concrete production. The availability of natural sand for concrete production is facing challenges, while the socalled waste stockpiles at aggregate crushing areas are causing problems for producers.
