1.0 INTRODUCTION Concrete is generally composed of aggregates, cement and water. The aggregates are usually coarse and fine aggregates. Cement is used for binding the concrete materials together. Coarse aggregates have particles bigger than 5 mm in diameter while fine aggregates have particles smaller than 5 mm in diameter. Cement is hydrated to form a gel …

This study aimed to research the influence of Mogadishu-manufactured sand on the engineering properties of concrete. Manufactured sand refers to fine aggregate which is less than 4.75mm. In this research, Mogadishu Manufactured sand was refined from the crushed limestone rock as a replacement for river sand.

1.1 Crushed Rock Dust (CRD) Quarry waste fine aggregate, which is generally referred as a CRD, causes an environmental load due to disposal problem. Hence, the use of CRD in concrete mix will reduce not only the demand for natural sand but also the environmental problem. In brief, the successful utilization of CRD will turn this waste

reduce the use of natural sand by using crushed rock powder(CRP) as a replacement for fine aggregate in concrete .Thereby reducing the exhaustion on natural sand. The project involves the process in which fine aggregate in concrete is replaced by CRP at 0%, 20%, 40% and 60% replacement. Grade of concrete M25 is selected for the project.

The present investigation aims in the study of properties of mortar and concrete in which Crushed Rock Powder (CRP) is used as a partial and full replacement for natural sand. For mortar, CRP is replaced at 20% 40%, 60%, 80% and .

crushed sand. Better for strength and durability performance to replace river sand and conventional stone in the production of concrete for use in rigid pavement for rural areas. 4. …

Natural sand was replaced with Quarry dust by three proportions (i.e. 10%,20%, and 30%). The study was carried out on M20 grade concrete with 0.5 water cement ratio. Quarry dust can be used as fine aggregate, but it has to satisfy …

This paper presents the fresh and hardened properties of high-strength concrete comprising byproduct fine crushed aggregates (FCAs) sourced from the crushing of three different types of rocks, namely granophyre, basalt, and granite. The lowest void contents of the combined fine aggregates were observed when 40% to 60% of natural sand is replaced by the FCAs. By …

replacement of natural sand with mount crushed rock sand. It means that we prepared 9 blocks for compression test. After that the specimens are cured in mould for 24 hours. After 24 hours, all samples are removed from the mold and kept in the healing tank for 28 days. After days all weight samples are kept in

The present investigation aims in the study of properties of mortar and concrete in which Crushed Rock Powder (CRP) is used as a partial and full replacement for natural sand. For mortar, CRP is replaced at 20% 40%, 60%, 80% and .

The use of crushed rock powder as a partial replacement of sand in concrete not only results in conservation of natural resources but also helps in maintaining good environmental conditions and also reduces the scarcity of naturally …

A 15% replacement slightly reduced both strength and durability. (Premalatha & Srinivasan, 2019) analysed concrete properties by replacing river sand with glass powder. Testing various concrete grades with up to 50% glass powder replacement for fine aggregate, they found improvement in strength up to 30% replacement.

observed by replacing natural sand by CRP at different levels of replacement namely 20%, 40%, 60% 80% and . In the second stage, the finer particles in CRP, finer than 150 micron are removed by screening and this modified CRP is named as Conditioned Crushed Rock Powder (CCRP) and is used as replacement of sand in mortar.
