Abstract:

The primary purpose of this investigation was to study the feasibility and effects of sulfur impregnation of concrete carried out at atmospheric pressure. The investigation had three parts: to study the effects of process technology parameters (mix proportions, time of curing, temperature of drying and time of immersion in molten sulfur bath), to analyze the effects of high temperature and temperature cycling on properties of impregnated concrete, and to explore the possiblility of improving strength and ductiliy of SIC by addition of steel fibers.

Abstract:

Laboratory experiments are reported with the intention to show the effects of epoxy modification of portland cement mortars in the presence or absence of accelerating and/or plastifying admixtures. . .The test results show considerable improvements in the workability of the epoxy-modified mortars, and strength increases, when it accelerating admixture was also used, up to 100 to 120%. It appears from the results of the silylation that these strength increases were caused mostly by physical factors.

Abstract:

For evaluating the performance of concrete constructions such as foundation piles, a knowledge of the dynamic properties of concrete is also required. The results of a study of concrete under dynamic impact loading are given in this paper.

Abstract:

By applying the newly developed techniques of polymer impregnated concrete (PIC) in conjunction with existing epoxy repair technology, severely deteriorated, low quality concrete can be restored to an adequate structural material. The problem of handling techniques and safety of PIC used in a closed building environment are discussed along with costs of commercial use.
