Effect of Shrinkage Reducing Admixture on Drying Shrinkage

The reduction of the moisture content of concrete during the drying process reduces the concrete's volume and causes it to shrink. In general, concrete shrinkage is a phenomenon that causes concrete volume to dwindle and can lead to durability problems. There are different types of this phenomenon, among them chemical shrinkage, autogenous shrinkage, drying shrinkage including free shrinkage

Experimental Study on Modification of Concrete with

Concrete resistance to weathering actions and chemical attack can be improved by combined chemical and mechanical modification of concrete microstructure. Asphalt admixture in the form of asphalt paste (AP) was used for chemical modification of cement composite microstructure. Concrete structure was formed using special technology of compaction.

Effects of Shrinkage Reducing Agent and Expansive

This paper investigated the influences of shrinkage reducing agent and expansive admixture on autogenous and drying shrinkage of ultrahigh performance concrete (UHPC) containing antifoaming admixture. The shrinkage reducing agent was used at dosage of 0.5%, 1%, and 2% and the expansive admixture was used at dosage of 2% to 4% by mass of cementitious material.

Self-Healing Concrete with Crystalline Admixture—A Review

The scope of the present paper is to understand the effects of crystalline admixture on the self-healing capacity of the cementitious composites. Previous studies were examined and a conclusion was drawn to the effect that different additives to crystalline admixture tend to improve self-healing of concrete for larger cracks. It is recommended that initial treatment with chemical admixture can

Video: Considerations of colored concrete | The American

Concrete can be colored in a variety of ways, including through staining, dyeing, and integral color, which is when pigment is blended into the cement. Integral color is one of the most popular methods for coloring newly placed concrete, and the video below explains some of the considerations that go into using integral color. YouTube.
