Manufactured aggregates are less likely than gravel and sand to be contaminated by deleterious substances such as clay minerals or organic matter. However, large crushed powder content is the major concern for crushed sand. The crushed powder content may affect the water required and the workability of concrete.

Lightweight aggregate concrete manufactured by solid waste or recycled by-products is a burgeoning topic in construction and building materials. It has significant merits in mitigating the negative impact on the environment during the manufacturing of Portland cement and reduces the consumption of natural resources. In this review article, …
B) Fine Aggregate-Fine aggregate includes the particles that all pass through the 4.75 mm sieve and retain in the 0.075 mm sieve. Locally available manufacture sand i.e.M-sand will be used as fine aggregate. The sand will first be sieved through a 4.75 mm sieve to remove any particles greater than 4.75 mm and then washed to remove the dust.
Waste foundry sand is used as feed to kiln in Portland cement manufacturing and as substitute to fine aggregate in construction purposes. Most of the WFS from green sand castings is land-filled and sometimes is …
Abstract. Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new …
For. usage in concrete, an ideal clay lightweight aggregate should be generally spherical, 4 – 14 mm in. diameter, robust, and porous. Clay's porous nature is a fundamental determinant of ...
The optimum compressive strength was found in variation 3 (40% M Sand + Waste Marble 50%) of 35.801 MPa at 28 days, with the optimum water absorption obtained at variation 1 (40% M-Sand + 0% Waste ...
The present study is focused on replacing conventional coarse aggregate ranging from 0 to 12.5% with e-waste plastic for M 20 grade concrete using manufacturing sand.
The results revealed that substituting river sand with EWS could augment the physical and mechanical properties of the unfired blocks. Some studies have investigated the viability of substituting natural aggregates with recycled concrete aggregate (RCA) and engineering waste soil (EWS) in masonry products.
Materials. The studies were based on six recipes of mixtures of plaster mortar. When choosing the proportions of ingredient and aggregate fractions use was made of a patented invention, namely plaster mortar based on Roman cement (Urban and Szeląg 2014).Mortar is primarily designated for repairs and renovation of old historical …
This work aims to study the possibilit y recycling of foundry sand wastes (FSW) as a cementations additive and fine aggregate in self-. compacting mortars (SCM). For th is, an experimental stu dy ...
The use of waste clay generated by major infrastructure development projects to make lightweight aggregate has a positive environmental impact and contributes towards a more circular economy.
