Waste Glass in Concrete; Pros and Cons - Concrete Decor

Dec 14, 2019 · Waste glass comes in a variety of sizes, from a fine powder and sand grain pieces to small and larger aggregates. Another reason why glass containers can't be recycled efficiently is the source of the waste glass. Usually, people mix waste glass, such …


The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates. In that case, the aggregates considered are slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.

Simple Waste Water Treatment For Concrete Producers

To simply discharge untreated waste water off the property can incur a liability for fines but also for future fees for remediation of the property upon which the water was discharged. In 2011, a company operating ready mixed concrete plants was fined $740,000 for violating the Clean Water Act. The company also was required to pay $8,000,000


normal concrete mix. Splitting strengths ranged from 10 to 15 percent of the compressive strength. The use of residue as aggregate in PCC is compli­ cated by a potential alkali-glass reaction. Johnston (~ found this to be true when he substituted waste glass for coarse aggregate in concrete…

Protecting Concrete Tanks in Water and Wastewater

Dec 28, 2000 · The rate at which concrete deteriorates is a function of two factors: the quality of the concrete and the environment to which the concrete is subjected. The quality of concrete refers to the properties incorporated into the original concrete mix design such as water/cement ratio, cement type, size and hardness of the aggregate and air entrainment.

Cement and Concrete: Environmental Considerations

Mar 01, 1993 · There are approximately 210 cement plants in the U.S. and 4,000 to 5,000 ready mix plants (where cement is mixed with aggregate and water to produce concrete).

A Greenhouse Study of Concrete Grinding Residue Influences

May 16, 2020 · Concrete grinding residue (CGR) is a byproduct of diamond grinding, a road surface maintenance technique. Direct deposition of CGR along roadsides may influence plant growth, which has not been fully studied. Particularly, systematic experiments of CGR effects on selected common prairie species growth under controlled environments are rarely reported. Thus, in this study, a greenhouse
