Coarse Aggregate: Coarse aggregate is obtained by crushing quarry rock to required size. The pieces of crushed stone varying from 5mm to 80mm size can be called coarse aggregates. The size of the aggregate that is to be used depends on the type of work. Most of the times 20mm to 40mm size aggregates are used in R.C Works.

Materials Used The materials used in this experiment were cement, Granite powder, fine aggregate, coarse aggregate and water. 1 ) Cement: OPC 53 grade cement conforming to IS 8112-1989, from a single batch was used throughout the course of the project work.
Aggregates consist of fine aggregates and coarse aggregates. Generally aggregate less than 4.75 mm is classified as fine aggregate. The popular and most preferred materials used as fine aggregates are river sand and crushed stones. However, river sand and crushed stone are produced at great cost and at the expense of
What Is Coarse Aggregate? The aggregates which are able to get retained on the 4.75 mm sieve or the aggregates that passes a size larger than 4.75 mm are referred to as Coarse aggregate.. One of the most important components of concrete is aggregate.The coarse aggregate provides concrete volume. The coarse aggregate in the concrete provides the …
GRANITE The application of granite in building construction involves bridge piers, retaining walls, dams, curbs, stone columns, as coarse aggregate in concrete, ballast for railways, as damp-proof course and external cladding of walls, and monumental utilizations. The structure of granite is crystalline, fine to coarse grain.
3.4. Coarse aggregate The materials which are retained on a 4.75mm sieve are called coarse aggregate. Coarse aggregate forms the main matrix of the concrete. The nature of work decides the maximum size of the coarse aggregate. Locally available coarse aggregate having the maximum size of 20 mm was used in the present study
Crushed waste mosaic tiles, crushed waste and Granite powder are used as a replacement to the coarse aggregates and fine aggregate. The waste crushed tiles were partially replaced in place of coarse aggregates by 10%, 20%, 30%, 40% and 50%. Granite powder was replaced in place of fine aggregate by 10% along with the ceramic coarse tile. M25
granite stone angular in shape was used as coarse aggregate. The properties of the materials are presented in Table 1. Table – 1 Properties of the constituent materials Sl.No Parameter OPC used Brick Powder Fine Aggregate Coarse Aggregate 1 Normal Consistency 29% - - - 2 Fineness by Sieving (%) 90 micron mesh 80 - - -
Basic changes in both type of aggregate properties were determined by various test as per require IS code, thus, it is a suitable to use Stone Chips as coarse aggregate or partial replacement with ...
B.Kavitha et al /International Journal of ChemTech Research, 2017,10(8): 74-80.75 friendliness, and energy conserving implications Research has been conducted on the use of fly ash, volcanic ash, volcanic pumice, pulverized-fuel ash, blast slag and silica fume etc. as cement replacement material4. Fly
aggregate as partial coarse aggregate replacement. Granite aggregate has been replaced by 10, 20, 30, 40 and 50% with laterite aggregate. All the specimens were subjected to water curing until it is ready to be tested. Tests on compressive strength, flexural strength and modulus of elasticity were carried out at the age of 7, 14, 28 and 60 days.
replacement with sand, in this study to investigate partial replacement of fine aggregate by quarry dust in various percentages and also the effect of partial replacement of cement by fly ash at the time of preparation of SCC. Coarse aggregate of size 20mm maximum size and minimum powder content up to 400kg/m. 3. without VMA is used. Super

mixing proportion of river gravel and granite that will give the required workability and strength of concrete which in essence will minimize the amount of cement paste used in concrete production . 1.1. Aim and Objectives The aim of this study is to unveil the effect of coarse aggregate type on the compressive strength of concrete.
Experimental Study on Granite Powder as a Replacement of Fine Aggregate in Concrete Anandhu Ramesh,Saravanan.S, Kanesh Pandian.M,Charles Raja.P ... granite stones are machined from the quarries and the blocks are transported to nearby ... alternative both fine and coarse aggregate has become necessity for the construction industry because of the
In the present study, the generated waste was used in lean cement concrete as a replacement of conventional coarse aggregate in different percentages 20–100% by weight. The idea of working on lean concrete mixes was maximum utilization of marble waste which saves the natural resources. 2.
FINE AGGREGATE AND COARSE AGGREGATE: Fine and coarse aggregate make up the bulk of concrete mixture. Sand, natural gravel and crushed stone are mainly used for this purpose. For fine aggregates natural sand is provided with maximum size of 4.75 mm. coarse aggregates are used with size between 20mm-4.75mm
