crushed aggregates as substitute to sand in concrete

Alternative fine aggregates in production of sustainable

Utilization of alternative fine aggregates is the hour of need for sustainable construction. • The alternative fine aggregates satisfies the requirements as alternatives to river sand. • Crushed rock sand, industrial by-products and recycled fine aggregates Primary aggregate substitutes: concrete sand, round (SR), concrete sand, broken (SB), marble (MA), amphibolite (AM), granodiorite (GD); basalt (BA); Life Cycle Assessment of River Sand and Aggregates Alternatives

Study on Replacement of Sand in Concrete with Crushed

The suitability of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete made with natural sand. Crushed stones, sand, rock quarries, and gravel are the most common materials used as aggregates, while recycled concrete and marine aggregates The Production of Sustainable Concrete with the Use of

Use of waste ceramics to produce sustainable concrete: A review

A large amount of water, cement, natural aggregates (NA), and river sand, is being used in concrete manufacture Self-compacting concrete: Crushed Ceramic waste(7 mm, 12 (2018) examined the utilization of recycled coarse ceramic aggregates to substitute CA in concrete. The recycled ceramic CA produced in the brickNatural sand was replaced at 10%, 20% and 30% with the crushed window waste glass.

Full article: Strength and microstructure of eco-concrete produced

The obtained results clearly suggest that glass sand cannot be used to produce eco-friendly concrete by using more than 50% glass sand as a substitute for natural sand in order to ensure the production of moderate strength concrete of Knowledge Institute of Technology. Manufactured sand blended with natural sand in the ratio of 70:30 can be used as fine aggregate in concrete, which shows the better performance than conventionalCan someone suggest an alternative of sand as a fine aggregate in concrete?

Effects of different industrial waste materials as ScienceDirect

Makhloufi et al. [22] explored the performance and mix proportion of limestone as fine sand in concrete. The result delineates that crushed limestone in concrete mix has more water demand, but when the water content in the mix is increased the concrete strength decreases. Nevertheless, the compressive strength of concrete Concrete is currently the most consumed construction material in the world, and China consumes about 1.4 billion cubic meters of concrete and 20 billion tons of sand and gravel aggregates every year [].The production of cement consumes a large amount of limestone, clay and coal resources and produces a large amount of CO 2, Advances in the application of crop residues as aggregates and

Structural Performance and Characteristics of Concrete with Crushed

One of the substitute material that comes to mind as a solution to this Rise straw ash are some of the proved significant replacements of sand and cement in concrete. Crushed glass is being studied for use in concrete for partial replacement of cement, sand and aggregates. It is used in crushed form as fine or coarse aggregatesthe Australian context. The use of RGS in concrete as a sand substitute did not have a high environmental footprint. However, global warming effects was reduced consequently, as a part of cement was replaced by RGP. RGS concrete and RGP concrete can reduce ozone layer depletion up to 14% and 22%, respectively.Use of waste glass as aggregate and cement replacement in concrete

Use of Waste Window Glass as Substitute of Natural Sand in Concrete

This paper investigates the production of low-cost, high-strength concrete by partially replacing fine aggregates (FA) with waste glass sand (WGS). Four concrete mixes were considered in thisUtilization of glass powder waste for concrete mixtures is now being developed. This research was conducted to determine the optimum composition of glass powder as a partial replacement of sand against the compressive strength of concrete. The content of the glass powder mixture used is 10%, 15%, 20%, and 30% of the weight of Effectiveness of Glass Powder as a Partial Replacement of Sand in
