granite fines content was the optimum value for improved structural performance. Kanmalai Williams C et al (2008) examined the performance of concrete made with the granite powder as fine aggregate. Sand was replaced with granite powder in steps of 0, 25, 50, 75 and and cement was replaced with 7.5%Silica fume, 10% fly ash and 10% slag.
Specifically, the study sought to look for possibility of substituting sand with crushed granite tile. Experimental design was implemented to determine the significant difference between cement mortar with crushed granite tiles as aggregate and that with sand as the fine aggregate, in terms of compressive strength.
Typically, coarse aggregate sizes are larger than 4.75 mm (5 mm in British code), while fine aggregates form the portion below 4.75 mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as .
fine aggregate (sand) and cement were partially replaced with Granite powder and marble powder. The replacement is done by 5%, 10%, 15%, 20%, 25% of cement by marble powder and 5%, 10%, 15%, 20%, 25% of fine aggregate by granite powder to evaluate the effect of presence of these replacement materials on the strength of specimens.

granite powder as fine aggregate replacement. Granite waste because of its fineness and size it can be effectively used as a replacement of fine aggregate. Granite powder sourced from local natural stone processing plants and Flyash sourced from industrial waste. In this study, granite .
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and ...

cast. During the present study, the fine aggregate was replaced with granite powder and the percentages of granite powder added were 0, 10, 20, 30, 40 and 50% of fine aggregate. 3.3 Mixing of concrete: The performance of the concrete is influenced by the mixing. This means that a .
fine aggregate and coarse aggregates. To meet requirements we can utilize alternative materials for coarse and fine aggregates such as crushed stones (Granite and Basalt as ingredients) of desirable sizes and river sand as fine aggregates in conventional concrete. While preparing mortar

Properties of Aggregates and its Values for use in Construction. Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
In locations where crushed granite fine is readily available and river sand tend to be more expensive the use of 80% crushed granite fine plus 20% river sand as fine aggregate is recommended for use in the construction of low to moderately trafficked rigid pavement.
Nevertheless, in many parts of the world such material is a major source of fine aggregate. In Jamaica, 'stone dust' is produced as a by-product of limestone quarrying and is used, principally, in concrete block making and in asphalt products. The quality of the 'stone dust' is, however, variable and may perform poorly as fine aggregate.
1. Expanded Polystrene(EPS): EPS balls are used as an aggregate instead of the crushed stone that is used in regular concrete, it known as EPScrete, EPS concrete or lightweight concrete. It has been used as road bedding, in soil or geo-stabilizat...
The materials used in this study were ordinary Portland cement CEM I 42.5 grade, conforming to British Standards, granite of maximum particle size of 12.5 mm and granulometric modulus of 6.95, river sand of maximum particle size of 4 mm and granulometric modulus of 2.24, ceramic waste coarse aggregates of granulometric modulus of 6.88, ceramic fine aggregate of granulometric modulus of 2.20 ...
Nov 06, 2016· In the present study, granite dust was chosen as a fine aggregate and Portland cement was added to the mixture that can be acted as a binding agent. The present study highlights the strength behavior of concrete cubes containing granite dust as a fine aggregate associated with variable mixtures of Portland cement.
