The environmental impact of concrete, its manufacture and applications, are complex. Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil. Concrete is used to create hard surf

120m³/h Concrete Batching Plant. HZS120 is a large and medium-sized concrete mixing plant made by Camelway, suits for mixing dry hard, half dry hard, plastic, and other ratios of concrete with features of high production efficiency, high mixing quality, stable and reliable, long lifespan etc.

Where shafts are to be sunk wet (ie material is removed from below the water level in the shaft), there is a risk of the water in the shaft becoming highly alkaline when the concrete base is poured. When using dry-mix concrete to set kerbs or paving, water that runs off may be alkaline and, if so, needs to be contained.

concrete batching plant is a designated development under Section 77A of the Environmental Planning and Assessment Act, 1979 with a capacity to produce more than 30,000 tonnes per annum of concrete.

1,300 are drum mix plants. The total 1996 HMA production from batch and drum mix plants is estimated at about 240 million tons and 260 million tons, respectively. Based on these figures, an average batch mix plant produces approximately 100,000 tons of HMA annually, and an average drum mix plant produces about 200,000 tons of HMA per year.

Concrete batching consists of producing concrete or concrete products by mixing cement with sand, rock, aggregate or other similar materials. In a concrete batching plant, the raw materials are mixed using a front end loader or overhead bin concrete batching techniques.

assessment carried out for handling of wet and dry concrete materials, e.g. when loading mixer and when pouring and shovelling concrete into position. Mixer to be mounted on wheels to ease movement around site. Half bags to be used wherever possible – full bags to be split in two before loading into mixer.

This site task risk assessment form for works involved in the mixing or laying of mass concrete slabs or foundations will allow you to assess the risks to your employees while carrying out this task. This risk assessment form has been professionally written for you to use by adding to or deleting the control measures that we have suggested.

Whether you are mixing up a batch of concrete, using cement in other ways, or drilling into concrete materials, you may be exposed to cement and concrete dust. It might not be possible to eliminate cement and concrete, but it is possible to use cement and concrete safety by controlling the risks.

More information on assessing and controlling this risk can be found in the section on construction dust. Control. Prevent: Where possible think about eliminating or reducing the amount of cement used and contact with it. Consider: avoiding exposure to cement powder by using pre-mixed concrete / mortar
