Available in PDF, EPUB and Kindle. Book excerpt: Portland cement and grout are construction materials used in widely varied types of structures. One of the major disadvantages of these materials is drying shrinkage. Researchers have worked on this problem for many years, and technology has advanced to the point where products are now being manufactured which when used in protland-cement concrete can cause expansion to counteract shrinkage or, depending on amounts used, cause positive expansion. Two expansive mixtures were investigated in the program described herein: Type K expansive cement, which consists of portland cement clinker, anhydrous calcium aluminate sulfate, lime (CaO), and calcium sulfate (CsSO4); and Type M expansive cement, which is a mixture of portland cement, calcium aluminate cement, and calcium sulfate. The purpose of the research effort was to develop expansive concrete and grout mixtures for use in structures in connection with underground nuclear testing. (Author).

This book was released on 1965 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known for more than a century that the reaction of calcium aluminate with sulfate ion to form calcium sulfoaluminates (or 'calcium aluminum sulfates') is accompanied by an increase in volume. During most of this period, the reaction has been regarded wholly as a harmful one, the consequences of which are deteriorative or destructive to concrete. This report attempts to review and summarize available information on expanding cements, as developed both in the United States and elsewhere, from the standpoint not only of the chemical and physical mechanisms involved, but also of the potential and actual applications that might be made of these products by the Corps of Engineers. Beginning with the work of Lossier in the 1940's, continuing with work in the U.S.S.R. in the 1950's, and the work of Klein and associates in the United States in 1958, this reaction has been studied with a view to employing the resultant volume increase to achieve beneficial results. The general consensus is that much basic knowledge needs to be obtained regarding the numerous potential expansive combinations of materials to relate their behavior to the specific physical-chemical mechanisms that are involved. It also appears to be true that, in spite of major gaps in fundamental knowledge, certain specific formulations involving specific materials have been and are being used successfully in full- scale engineering applications.

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory evaluations were made of 14 grout mixtures and 7 concrete mixtures, all of which contained type K expansive cement wholly or in part. The mixtures were developed for field use on a number of different projects. They varied widely in ingredients, proportions, curing, and the type of evaluations made. Very few direct comparisons of behavior among mixtures could be made. Three special control study mixtures were also evaluated as a pilot study. Both shrinkage-compensating and self-stressing type K expansive cements were used. The self-stressing cement was used as a portion of the total cement, while the shrinkage-compensating cement was used as the only cement in the mixture. Each mixture was evaluated for some, but not all, of the following: expansion, strength, modulus of elasticity, compressional wave velocity, constrained pressure, temperature rise, slump loss, and efflux time. Comparisons were made as appropriate. Temperature rise values as high as 178 F were recorded. The various mixtures developed 3-day compressive strengths ranging from less than 1300 psi to more than 4700 psi. Maximum compressive strength noted was 7155 psi on one mixture at 28 days age; other 28-day strengths on other mixtures were as low as 2115 psi. Restrained expansions were always less than unrestrained expansions. Compressional wave velocities from 10,800 to 14,395 fps were observed. (Author).
