[ClickPress, Fri Sep 28 2018] Construction chemicals are broadly used for waterproofing repairs, bonding agents, crack and expansion joint fillers, tile adhesives, retarders, plasticizers, air entraining
compounds accelerators and others.
In plateau climate conditions, air entraining concrete is used in hydropower, transportation, and civil engineering projects to resist the frequent freeze-thaw cycle to avoid freezing and other induced disease, thereby ensuring the safe operation of the building .
The factors of ambient temperature, humidity, and air pressure affect the air entraining concrete performance besides the factors of raw materials, proportion of mixture, and construction method.
471 pounds, minimum cement per cubic yard: 686 pounds, admixture: air entraining
, water reducing.

admixtures' (AEA) limitations in the presence of unburned Class C or Class F fly ash carbon.
Also some additives such as a superfluidizer containing polymer of polyacrylic acid and an air entraining
admixture were added.
The chemical admixture was an air entraining
and water reducing agent.
We have studied then the chloride diffusion as a function of the slag content or other substituting materials of cements as well as the presence of air entraining
agents (see details Section 3).
The segmentation by type includes Superplasticizers, Normal Plasticizers, Accelerating Agents, Retarding Agents, Air Entraining
Agents and Waterproofing Agents and others.
However, the required concrete air content can be achieved by increasing the dosage of air entraining
Attributing to the addition of air entraining
agent, unique pore structures are formed, which improve the frost resistance of air entrained concrete.
For number 1 sample, air entraining
admixture was added.
