Performance of recycled waste glass sand as partial replacement of sand

This research studied the use of mixed coloured soda-lime glass supplied by Cairns Regional Council, Australia as sand replacement in concrete. 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 From the concrete studies, replacement of 20% of sand with crushed limestone dust improved the compressive strength of the concrete specimen, which is considered a significant enhancement in the strength. Overall it was found that crushed limestone enhances most of the properties and with 20% optimum replacement, the Impact of crushed limestone dust on concrete’s properties

Partial Replacement of Sand with Waste Glass in Concrete

To address the cement/concrete industry’s environmental and economic challenges, Malik et al. (2013) used waste glass as a partial replacement for fine aggregates (sand) in concrete. Several samples were made by replacing sand with glass contents of 10%, 20%, 30%, and 40% by weight in M-25 grade concrete.The samples were tested Concrete was produced by replacing natural river sand with 20%, 40% and 60% of recycled glass sand. In this study, mixed-colour soda lime glass, collected by Cairns Regional Council, Australia was used. The test results showed a significant improvement in the strength of concrete.Performance of recycled waste glass sand as partial replacement of sand

Use of fine recycled concrete aggregates in concrete: A critical

Although the use of fRCA in structural concrete was reported to have positive environmental impact [38], studies have indicated several issues when using fRCA regarding fresh and hardened properties of new concrete.For example, high water absorption of fRCA may lower concrete workability; adhered mortar introduces more fine 3.1.1. Coarse sand fractions (0.125/2, 2/5 and 5/8 mm) used for the experimental series A of the study. 0.125–8 mm partly natural sand fractions from Årdal (NSBR) sandpit.

REPLACEMENT OF NATURAL SAND IN CONCRETE BY WASTE PRODUCTS

The replacement of sand with stone dust at various ratios in medium-grade concrete showed an increase of up to 40 and 29% in compressive and up to 53 and 32% in flexural strengths for 7- and 28This paper examines the possibility of using crushed brick as coarse and fine aggregate for a new concrete. Either natural sand, coarse aggregates or both were partially replaced (25, 50, 75 and 100%) with crushed brick aggregates.

Cleaner production of concrete by using industrial by-products as

The use of natural sand is not sustainable anymore due to the global sand crisis. Coal mine overburden sand (OBS) and crushed granite sand (M-Sand) are two inert and technically sound alternatives of natural sand. Processing these sands to application specifications may lead to environmental impacts that need to be quantified.When you are developing a concrete product with natural sand, opportunities for improvement are scarce. But with crushed sand, there are more opportunities: there is a wider range, and you can find the best fit for different types of concrete. A totally different hurdle is the acceptance of the use of crushed sand in the A promising future for manufactured sand Aggregates Business

Use of recycled fine aggregate in concretes with durable

Different regulations specify a maximum water/cement ratio (w/c) in concretes with durable requirements. The Spanish Code (EHE, 2008) and the American Code (ACI 318, 2008) indicates maximum w/c ratios 0.45 and 0.40, respectively, while in the case of Argentinean Regulation (CIRSOC 201, 2005) the maximum w/c ratio is the Australian context. The use of RGS in concrete as a sand substitute did not have a high environmental footprint. However, global warming effects was reduced consequently, as a part of cement was replaced by RGP. RGS concrete and RGP concrete can reduce ozone layer depletion up to 14% and 22%, respectively.Use of waste glass as aggregate and cement replacement in concrete
