Crushed stone sand has been identified as a potential substitute material for natural sand in making good quality concrete. The main objective of the present investigation is to determine an adequate mix design method and evaluate engineering properties of crushed limestone sand concrete mixtures in both the fresh and hardened sates.
The research findings revealed that the distinctive surface qualities of crushed sand facilitate the production of high-strength concrete exhibiting an impressive slump range of 18.5 to 22 cm. remarkably, concrete samples exhibited commendable compressive strengths ranging between 114 and 122 MPa and 138 to 150 MPa at the 7 …
This paper discusses an experimental work on concrete made from river and crushed sands such as quartzite, granite, gneiss, marble, dolomite, basalt and …
The physical (workability, fresh density), mechanical (compressive and flexural strength) and thermal (thermal conductivity) of different crushed sand concrete made are analyzed and compared to the respective controls. The use of rubber waste in crushed sand concrete contributes to reduce the bulk density and performance of sand concrete.
The majority of studies on using crushed sand as an alternative for some sand of river in concrete focuses on concrete grades up to M40. However, there is a dearth of material on HPC using higher grade concrete. This study delves into the utilization of crushed aggregate to supplant river sand, building upon the groundwork …
The suitability of Crushed granite fine (CGF) to replace river sand in concrete production for use in rigid pavement was investigated. Slump, compressive and indirect tensile strength tests were performed on fresh and hardened concrete.28 days Peak compressive and indirect tensile strength values of 40.70N/mm 2 and 2.30N/mm 2 respectively was …
Self Compacting Concrete (SCC) has had a remarkable impact on the concrete construction industry, especially the precast concrete industry. Crushed Rock Dust (CRD) and Marble Sludge Powder (MSP) are discarded in the nearby land and the natural fertility of the soil is spoiled. MSP and CRD can be used as filler and helps to …
In this research, concrete with a target characteristic strength of 32 MPa was produced by replacing natural river sand with 20%, 40%, and 60% of crushed recycled glass sand (RGS) to investigate the effect of replacement levels on fresh and hardened properties of concrete.
One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high …
Six representative parent rocks of sand, including limestone, quartzite, gneisses, granite, Basalt and Marble were selected to conduct a systematical research on the effects of various lithologies of manufactured sand on the workability, mechanism properties, volume stability and durability of manufactured-sand concrete. The …
The influences of fines content, methylene blue () value, and lithology of crushed sand (CS) on frost durability and strength of concrete were investigated, and …
Evaluation of area- and volume-based gradations of sand-crushed stone mixture by 2D images ... and Affecting Factors of the Overlapping Degree of Interfacial Transition Zones between Neighboring Aggregates in Concrete[J]. Journal of Wuhan University of Technology-Materials Science Edition, ...
Limbachiya (2008) evaluated the mechanical and durability-related characteristics of concrete with replacement ratios of natural sand/coloured glass sand ranging from 0% to 50% by mass. Decreases in slump and mix stability were observed for ratios higher than 30%.
The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand. Crushed sand particle though shaped, does not …
This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials. The study comprehensively evaluates the properties of RCA and RS, focusing on workability, impact resistance, abrasion resistance, and compressive …
The availability of natural sand for concrete production is facing challenges, while the so-called waste stockpiles at aggregate crushing areas are causing problems for producers.
The availability of sand in the growing demand of the construction industry will be a challenge due to a wide range of variability, cost, and, quality problems. This study aims to investigate normal strength concrete by …
One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high-strength self-compacting concrete. Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures.
Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl 2017).Extremely low …
