Using Fly Ash in Concrete - National Precast Concrete

May 08, 2010 · The quality of fly ash is important–but it can vary. Poor-quality fly ash can have a negative effect on concrete. The principle advantage of fly ash is reduced permeability at a low cost, but fly ash of poor quality can actually increase permeability. Some fly ash, such as that produced in a power plant, is compatible with concrete.

Aggregate in Concrete - Concrete Network

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.

FOR QUALITY CONTROL PERSONNEL

Residential and light commercial mix designs (i.e. performance based, non-specified mixes) should be targeted first. Once these mix designs have been adjusted, the focus should shift to high strength mixes. Additional quality testing should be conducted at this point on a mix by mix basis to achieve maximum cementitious reduction.

Types of Ready Mix Concrete Plants and their Mixing Actions
