ACI SP-173:1997 PDF Download

ACI SP-173:1997 is a standard that consists of the proceedings from the Fifth CANMET/ACI International Conference on Superplasticizers and Other Chemical Admixtures in Concrete. The conference took place in October 1997 in Rome, Italy and aimed to exchange knowledge and technology in the field of chemical admixtures. The conference received over 60 papers from more than 20 countries, and 49 of them were accepted for publication in the proceedings.

The table of contents of the standard includes various topics related to the use and application of chemical admixtures in concrete. The papers cover subjects such as the mechanical properties of modified reactive powder concrete, the influence of characteristics of sulfonic acid-based admixture on the fluidity of cement paste, the electrochemical behavior of steel bars in mortars with nitrite corrosion inhibitors, and the use of condensed polyacrylic acid-aminated polyether polymers as superplasticizers for concrete.

Other topics discussed in the standard include the influence of hydrophobized concrete on the corrosion of rebars, the protection of reinforcements from chloride attack using galvanized steel and calcium nitrate, the properties of methacrylic water-soluble polymer as a superplasticizer for ultra-high-strength concrete, and the influence of vinyl polymers on the characteristics of polymer-modified mortars.

Furthermore, the standard covers research on dispersion mechanisms of alite stabilized by superplasticizers containing polyethylene oxide graft chains, blending of acrylic superplasticizer with napthelene, melamine, or lignosulfonate-based polymers, the interaction between Portland cement hydrates and polynaphthalene sulfonates, and the influence of chemical admixtures on the restrained drying shrinkage of concrete, among others.

This standard provides a comprehensive collection of research papers on the latest developments and applications in the field of chemical admixtures for concrete. It serves as a valuable resource for researchers, engineers, and professionals involved in the concrete industry.
