471 pounds, minimum cement per cubic yard: 686 pounds, admixture: air entraining
, water reducing.
Caption: The Tech Brief illustrates air entraining
admixtures' (AEA) limitations in the presence of unburned Class C or Class F fly ash carbon.
Attributing to the addition of air entraining
agent, unique pore structures are formed, which improve the frost resistance of air entrained concrete.
The segmentation by type includes Superplasticizers, Normal Plasticizers, Accelerating Agents, Retarding Agents, Air Entraining
Agents and Waterproofing Agents and others.
The chemical admixture was an air entraining
and water reducing agent.
Construction chemicals are widely used for waterproofing repairs, crack and expansion joint fillers, bonding agents, tile adhesives, plasticizers, retarders, air entraining
compound accelerators and others.
However, the required concrete air content can be achieved by increasing the dosage of air entraining admixture.
Two out of these four admixtures included different types of air-entraining agents, a vinsol resin-based air entraining agent, and synthetic-type air entraining agent.
In general, mixtures prepared with synthetic air entraining agent exhibited a more stable foam system [in tests] than mixtures prepared with vinsol resin-based air entraining agent.
In this research, Frost & Sullivan's expert analysts thoroughly examine the following admixtures: accelerating, retarding, plasticizing as well as superplasticizing, and air entraining
