Jun 01, 2017· Trial mix design were conducted to obtain the target strength of 35 MPa at 28 days with a workability of 100–125 mm as per American Concrete Institute ACI 211.1 (ACI, 2009).The glass powder replacement in cement was varied (0–25%). Mix proportion of concrete is shown in Table 6.Firstly, stone chips and sand were dry mixed for a minute.
Apr 10, 2020· The aim of this research is to utilize recycled waste glass effectively as a partial replacement for the sand in concrete. A series of tests were conducted to determine the properties of the constituents, fresh concrete, and hardened concrete including its durability characteristics to investigate the suitability of using recycled waste glass sand (RGS) in concrete.

Eco-friendly concrete production. They've discovered that glass waste can be used instead of sand – to create top quality prefabricated concrete panels for commercial and residential construction. This is a relief, considering the world is running out of sand, due to its over-extraction.
The mixture of concrete consists of 30% of sand. By replacing about 10% of it with plastic material, over 800 million tons of sand could be saved annually. In general, plastic materials weaken concrete as they don't bond to the cement mix in the same manner that sand does. Dr. Richard Ball, from Bath's Department of Architecture & Civil ...
