Building Materials. Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture.

Aggregate is a major ingredient for making concrete, occupy almost 70 - 80% part of concrete[1]. Conventionally crushed rocks are used as coarse aggregate and river sand used as fine aggregate.

It has been concluded that the dry density of sustainable concrete decreased to 4, 21.7, and 31.7% when crushed glass, clay brick, and rubber tire were incorporated into the concrete instead of ...

Besides powder, you can also use waste glass as an aggregate in concrete in the form of fine or coarse aggregates. Since aggregates occupy approximately 70% of the concrete, using glass cullet as aggregate in concrete does more than incorporate more waste glass in concrete. It also decreases the energy and time required to ground the glass ...

In this experimental setup, five mixes were prepared with different proportion of fine aggregate replacement. These five mixes are, control mix (M 0), M 1, M 2, M 3 and M 4, control mix is a standard mix having all natural fine aggregate content, whereas mix M 1, M 2, M 3 and M 4, contains 25%, 50%, 75% and of plastic fine aggregate …

Hebhoub et al. (), using the marble waste in the concrete manufacturing solves this problem environmentally and economically, especially with a 75% replacement value -of any formulation- under constant water to cement ratio.The use of the marble waste as replacement for coarse and fine aggregate separately or together leads to an …

Sawdust Ash (SDA) generated from rice mills is usually delivered to landfills for disposal. Using of sawdust ash in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural …

The coarse aggregate grade was between 4 mm and 10 mm in diameter for the granules. The waste materials replacing sand (see Section 2.1) are readily available without the need for further processing, with a particle size of less than 4 mm. A constant water-to-cement ratio of 0.45 was used in all concrete mixes.

The compressive strength test was conducted on the continuously water cured specimens at 7, 14 and 28 days. The results showed a perfect combination of fine laterite and fine palm oil clinker on S1 (25% of FL + 25% of FPOC) as partial fine aggregate replacement contributed towards enhancement of concrete strength.

The RCA is composed of coarse recycled concrete aggregate (CRCA) and fine recycled concrete aggregate (FRCA). The CRCA is a small concrete component made up of old coarse aggregate, mortar, and interfacial transition zone (ITZ), whereas the FRCA (>5 mm) is made up of crushed and sieved waste concrete mortar fragments.

The building sector continues to develop across the world. Concrete is a widely utilized building material in the construction industry. Cement, water, and fine and coarse aggregates are all basic materials used to create concrete (Bedi et al., 2013; Collivignarelli et al., 2020; Priyadharshini et al., 2021; Yalley & Sam, 2018).Indeed, the …

Abstract: Industrial silica sand is a by-product obtained from the industries like paint, paper, rubber etc. It has a similar property with river sand and& M sand. This study explores the effect of high content of silica sand as a partial replacement for fine aggregate for concrete making in construction purpose.

Abstract: This study aimed to explore the possibility of utilizing crushed glass as an alternative fine aggregate for concrete by replacing concrete with crushed glass. Specifically, the study sought to assess whether there is a significant correlation between crushed glass volume in concrete and its compressive strength and also between sand ...
