Marble Powder As Fine Aggregates in Concrete Marble industry contributes significantly to the socio-economic development of any country. Due to the abundance of marble reserves, Pakistan relies on marble industry, which in turn contributes to its GDP.
Reusing of waste glass in concrete production is among the attractive option of achieving waste reduction and preserving the natural resources from further depletion thereby protecting the environment and achieving sustainability. This present study examines the possible reuse of waste glass crushed into fine and coarse aggregate sizes as partial substitute for natural fine and coarse ...

Use of Crushed Granite Fine as Replacement to River Sand in Concrete Production Manasseh JOEL 86 Introduction Concrete is an artificial conglomerate stone made essentially of Portland cement, water, sand and coarse aggregates. The mixture of the materials results in a chemical reaction
aggregate replacement material in concrete production such as oil palm shell , periwinkle shell , recycled coarse aggregate  and others. However, to the best of author's knowledge no work has been reported on the use of cockle shells as partial coarse aggregate replacement in concrete .
Fly ash is another materials that has been used in partial replacement of cements in concrete and cement mortars, Jo et al. showed that fly ash based lightweightartificial aggregate is (2007) suitable for the production of concrete having a compressive strength of 29 N/mm2. Cold
However, another study demonstrated that using sawdust as partial replacement of fine aggregate up to 25% will contributes to reduction in sawdust waste generation without adversely affecting concrete strength . Close relations were predicted by using groundnut shells for partial replacement of fine aggregate in concrete .
obtained with the partial replacement of river sand with 20% CGF, as against values of 35.00N/mm2 and 1.75N/mm2 obtained with the use of river sand as fine aggregate. Based Experimental Investigation on the Effect of Replacement of Sand by Quarry Dust in Hollow Concrete Block for Different Mix Proportions
In this study, three types of construction waste namely floor tiles, clay bricks and crushed concrete aggregate were used to replace coarse aggregate in concrete production. The effect of coarse aggregate replacement on the workability, compressive strength, and flexural strength Grade 30 concrete were investigated and discussed.
Hence, partial or full replacement of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are being researched from past two decades, in view of conserving the ecological balance. Get Price
volume from table for the concrete using crushed coarse aggregates. Adjust the values of water content and percentage of sand as provided in the table for any difference in workability, water cement ratio, grading of fine aggregate and for rounded aggregate the values are given in table.
The dimensions of aggregates have direct effect on voids, water/cement ratio and workability of concrete mixtures. Therefore, the grain size composition of fine aggregate plays a fundamental role in the production of concretes and mortars, The results obtained for maximum diameter and fineness modulus were 2.42 mm and 2.36, respectively.

partial or full replacement of fine aggregates. Fine aggregate was replaced with CCB by weight up to 100 % at intervals of 10%. The properties investigated were: workability, density and the compressive strength. The slump test and the compacting factor test were used to assess the workability of the concrete sample specimens.
Assessment of Malaysian Laterite Aggregate in Concrete K.Muthusamy and N.W.Kamaruzaman Abstract— Integration of new material as a partial coarse aggregate replacement in local concrete production would be able to reduce the high dependency of concrete manufacturer on granite aggregate supply that may lead to ecological
Study of Concrete Involving Use of Waste Glass as Partial Replacement of Fine Aggregates 10 | P a g e 4.2. Hardened concrete The compressive strength tests and splitting tensile strength tests are presented in TABLE 3.
partial replacement for fine aggregate in structural concrete is particularly attractive. This project aimed to de-termine the level of glass replacement resulting in optimal compressive strength. Three concrete samples were tested at 7 and 28 days, for glass replacement proportions of 15, 20, 25, 30 and 40%. Compressive strength
