Micro fines are particles with a dimension of less than 75 microns in length and diameter. Micro fines are used in the production of M30 grade concrete in different proportions (0 %, 5 %, 10 %, 15 %, 20 %, and 25 %). Six Manufactured Sand mixes and one river sand mix were created for the purpose of testing and comparing them. The compressive ...
The production of manufactured sand and stone processing can cause dust pollution due to the generation of a significant amount of stone powder. This dust (mainly granite powder) was collected and incorporated as a cement replacement into mass-manufactured sand concrete in order to enhance the mechanical properties and microstructures. The heat of the …
Thus, there is a need for river sand and aggregates alternatives in concrete, namely manufactured sand (m-sand) from primary solid rock materials and secondary waste materials. The focus in the present study for …
In the literature, many works have focused on the quantification of how the concrete workability and durability could be influenced by using manufactured sand [6,12], especially its compressive behavior [1,11,13,14,15].In a series of papers, Shen et al. [3,13] have identified the influence of the shape of manufactured sand and roughness on the concrete compressive strength …
In the present investigation workability, strength and durability of concrete with manufactured sand as replacement to natural sand in proportions of 0%, 20%, 40%, 60% and is studied.
The increasing demand for river sand, driven by infrastructure development, poses environmental challenges. The study aims to address the depletion of river sand by integrating sea sand as a fine aggregate in the production of Self-Compacting Concrete (SCC) through a Systematic Literature Review. Furthermore, it includes an in-depth bibliographic analysis of …
The influence of fines content and features of manufactured sand on concrete properties are mainly analyzed. What's more, models of viscosity, modulus, and diffusion at …
In Australia, research conducted by Cement Concrete Aggregates Australia (CCAA) has provided greater confidence in the specification of manufactured sands for general applications in Australian Standard AS2758.1 (Aggregates and rock for engineering purposes) and in identifying suitable manufactured sands for use in concrete pavements.. …
Traditional natural river sand is used as a fine aggregate for concrete, but due to the severe environmental situation in recent years, many places have asked for a ban or restriction on the extraction of river sand. This …
Thus, there is a need for river sand and aggregates alternatives in concrete, namely manufactured sand (m-sand) from primary solid rock materials and secondary waste materials. ... The investigation of the test specimens destruction risk is a proven methodology in literature for the assessment of material durability [37,38,39,40]. Moreover, the ...
To understand the shape, texture, and mineralogical compositions of manufactured sand and laterite scraps accurately, SEM, EDAX, and XRD analyses were done, as shown in Fig. 3, Fig. 4.SEM images (Fig. 3, Fig. 4 a) indicate manufactured sand having lesser surface roughness than laterite scraps, which appear angular in shape.The EDAX …
This paper deals with the addition of optimum quantity of metakaolin as an admixture and partial replacement of river sand with …
Manufactured sand is also a kind of alternative aggregate with broad application prospects. Zheng et al. investigated the effects of fines on the durability of high-strength manufactured sand concrete. It was suggested that the fines content of high-strength manufactured sand concrete should be controlled within 5–15%, and the durability is ...
