Abstract:
With the aim of providing a perspective of the field of admixtures for the engineer confronted with a need of modifying concrete to meet special requirements of a given job, admixtures are classified into 11 groups. The 11 groups are: (1) accelerators, (2) retarders, (3) air-entraining agents, (4) gas-forming agents, (5) cementious materials, (6) pozzolans, (7) alkali-aggregate expansion inhibitors, (8) damproofing and permeablity reducing agents, (9) workablity agents, (10) grouting agents, and (11) miscellaneous. Discussions are given of the factors which might indicate the usefullness of admixtures of each group, and of the important effects which may ordinarily be expected from the use of materials of each group.
