Production of concrete and utilization of concrete has rapidly increased, which results in increased consumption of natural aggregate as the largest
The coarse aggregates used for the production of the control samples (normal concrete) were crushed granite stones obtained from single quarry site along ZariaSokoto road, opposite Nigerian College of Aviation Technology, NCAT Zaria. Sieve analysis was carried out on the coarse aggregates used in the experiment in accordance to BS 933 Part I (1997).
present study the feasibility of using Industrial sand () as a partial replacement of fine aggregates for the production of concrete has been explored.
concrete. The aggregates are classified into two categories: fine and coarse aggregates. Fine aggregates: The material which passed through Sieve No. 480 ()is termed as fine Impact factor make concrete dense, by filling voids of coarse aggregates, reduces the shrinkage of cement and makes an economical mix.
Cost of Concrete mix per is calculated on the basis of unit cost of each ingredient material in the mix. The following market rates have been taken for Cement, Sand, Coarse aggregate, Admixture and a nominal cost for water.
The river sand passing through mm was used as fine aggregate. Locally available 20 mm size blue metal jelly was used as a coarse aggregate. The specific gravity of the sand and the coarse aggregate was about and, respectively.

kernel shells as coarse aggregate; on the strength, weight in air and workability. The concrete was designed using British Building Research (BRE) method, and a total of 54 cubes were made of 150mm by 150mm by 150mm.
Additional models were developed to predict concrete properties of blended aggregate concrete for use in the design tools CRCP and JRCP described in previous reports. A computer program, CHEM2, was developed to allow the pavement designer to identify the material properties of concrete using an inexpensive chemical test.
aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the mm (No. 4) sieve and predominantly retained on the 75 µm (No. 200) sieve is called fine aggregate or sand, and larger aggregate is called coarse aggregate.
Spent Foundry Sand as Partial Replacement of Fine Aggregate in the Production of Concrete Augustine Uchechukwu Elinwa, Civil Engineering Department, Abubakar Tafawa Balewa University, Bauchi, PMB 0248, Bauchi, Bauchi State, Nigeria. Abstract: An evaluation on the use of spent foundry sand (SFS) in the production of concrete has been carried out.

Concrete made with just fine aggregate (or sand) is known as mortar concrete. Like the mortar used for brick and concrete block construction, which is simply made with mortar cement and sand, mortar concrete has no coarse aggregate in it, so a ground finish will have a finegrained appearance.

concrete production is very much helpful to reach the goal of the sustainable construction. Therefore, this study intends to use ceramic tile aggregate in concrete production. The paper reports on the performance of 3 different concrete mixes containing different ratios of crushed tiles having 20 mm maximum size as coarse aggregate.
(1). For sand with percentage clay/silt contents of 5% and 10% will produce concrete with compressive strengths of /mm2 and N/mm2 respectively, and the higher the percentage of clay/silt in sand the lower the concrete strength. It is very important to control the quality of the aggregate to be used in concrete making.
replacement of Plastic Aggregate in concrete stands suitable here are intended for the making of concrete recycled coarse aggregate taking dimension 20mm, normal waterway sand recycled for production a material also soft collection used in wrinkled concrete since the confirmed cubes.
The effects of size of coarse aggregate and cement content on the compressive strength of brick aggregate concrete have been reported in this paper. A total of 108 numbers of concrete cylinder (150mm×300mm) were tested using six
The strength of concrete products reused the third processed coarse aggregate increased 21% at 14day age and 17% at 28day age, compared with the concrete products reused the second processed coarse aggregate.
