This research aims to investigate the effect of using this recycled glass as fine aggregate replacement in concrete both at fresh and hardened states.
Recycled aggregates concrete (RAC) takes a responsible approach to resource management by utilizing construction and demolition waste as a substitute for aggregates like sand and gravel. This approach involves …
These cheap concrete substitutes are often sourced from construction waste, making them affordable and sustainable options. Ashcrete: A lesser-known alternative for sand in concrete, Ashcrete is made from fly ash, a byproduct of …
M sand (manufactured sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing.The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.
The study aims primarily to investigate and analyze the impact of incorporating glass sand as a substitute for natural sand in concrete mixtures at different dosage rates (0%, 10%, 20%, 30%, and 40%) on its physical and mechanical properties. Five concrete formulations were prepared and examined. The results of the workability tests, air ...

M{'e}ndez and Fredy …
Concrete and mortar specimens were made with different variables, such as replacement volume of natural sand with different alternative fine aggregates, water-to-cement ratio (W/C), and sand-to ...
Applying its signature Joule-heating technique to metallurgical coke, the Tour lab has created a type of graphene that could serve as a substitute for sand in concrete.
Researchers across the globe have attempted to utilize waste of copper slag, rubber tyre, recycled glass, pond ash, foundry sand, plastic, stone etc. as a partial or complete substitute of river ...
As environmental, transportation and other constraints make the availability and use of natural sands less attractive, a substitute or replacement product for the concrete industry needs to be found.
Ismail and Al-Hashmi used crushed waste glass (size 4.75–0.15 mm) to partially substitute natural sand in concrete at weight levels of 0, 10, 15, and 20%. According to the findings, the presence of discarded glass lowered ASR growth. As the volume of discarded glass increased, ASR decrease. Glass sand content has a substantial influence on ...
Natural sand is fast becoming a scarce resource. Scientists at the Indian Institute of Science (IISc) in Bengaluru have created a promising new material that can replace natural sand in construction.
The viability of coal mine overburden (CMOB) as a sustainable substitute for natural sand (NS) in concrete production is investigated in this study, with a specific focus on the critical aspects of strength and durability. The reliability of select nondestructive testing (NDT) methods for evaluating the mechanical and durability properties of CMOB-incorporated …
Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It …
Artificial or M-sand: M-Sand is recognized as a substitute for river sand due to the decrease in high-quality river sand. Manufactured sand is referred to as M-sand. It is produced in factories …
Concrete made with dredged offshore sand with partial replacement of river sand had compressive and flexural strengths equivalent to the concrete made with river sand.
The improved compressive strength by Fig. 5 Compressive strength values of RPC mixes at 7 and 28 days using CP instead of quartz sand at 5% is due to the increased amount of calcium silicate ...
Coal bottom ash can be used in concrete as a sand substitute material either partially or fully1. In the past several decades, the utilization of such industrial waste materials for substitute of sand in the preparation of concrete has contributed to superior properties in comparison with that of conventional concrete in terms of strength ...
used as a sand substitute in concrete. This research aims to investigate the effect of using this recycled glass as fine aggregate replacement in concrete both at fresh and hardened states. Natural sand was replaced at 10%, 20% and 30% with the …
Concrete is literally the foundation of our civilization. We use twice as much of it as all other building materials combined. But concrete is also a major contributor to global warming, producing 8% of carbon dioxide emissions …
The recycled waste glass was proportioned in levels of 25, 50, 75 and by weight to substitute sand in the concrete using a mix ratio of 1:2:4 (cement:sand:gravel) at a W/C ratio of 0.5 targeting 20 MPa strength at 28 days. Tests, which include X-ray fluorescence (XRF), were conducted on the waste glass and cement materials; slump test was ...
Quarry dust is a by-product from the granite crushing process in quarrying activities. This paper presents the findings from experimental work undertaken to evaluate the suitability of quarry dust as a partial substitute for sand in high-strength concrete (HSC) containing rice husk ash (RHA).
