Add Mixtures

Admixtures are added to concrete batch immediately before or during mixing concrete. Concrete admixtures can improve concrete quality, manageability, acceleration, or retardation of setting time, among other properties that could be altered to get specific results. Many, not to say all,concrete mixes today contain one or more concrete admixtures that will help your pouring process driving down cost while increasing productivity, The cost of these admixtures will vary depending on the quantity and type of admixture being used. All of this will be added to the cubic yard/meter cost of concrete

Air-entraining admixtures facilitate the development of a stable air-void system within concrete that increases the durability of the concrete. These admixtures impart air entrainment that results in:

• Increased resistance to deterioration from cyclic freezing and thawing
• Improved work-ability and cohesiveness of concrete placement
• Reduced segregation and bleeding

Mid-Range Water Reducers are used to reduce the water demand between 5% and 15%, achieve longer slump retention and give greater workability to concrete then normal ASTM C 494 Type A water reducers. High-Range Water Reducers are used to reduce water demand at 12 – 30%. Giving the best workability, having superior slump retention and aiding in the production of High Performance Concrete (HPC) and Self Consolidating Concrete (SCC).

Efflorescence Control Admixtures impair the movement of salts within the pores and capillaries of concrete products and minimize their impact on surface appearance
