This problem led ODOT to investigate a self-curing admixture (SCA) for bridge deck concrete mixes. The SCA reduces wet curing requirements by counteracting to some degree water loss due to evaporation. An admixture in place of wet curing that allows HPC bridge deck concrete to cure properly without early age cracking and without decreasing other performance requirements would provide …

Student, Structural Engineering Part Time (2013-2016), Bharathidasan Institute of Technology Anna University, Tiruchirappalli, Tamilnadu, India . ABSTRACT . In this study strength parameters of self-compacting concrete, self-curing concrete, Self-compacted self-curing concrete …
The concept of self-curing agents is to reduce the water evaporation from concrete, and hence increase the water retention capacity of the concrete compared to conventional concrete, . The aim of the investigation is to evaluate the use of water-soluble polymeric glycol as self-curing agent.
Today though there are various ready mix plasters and concrete with additives such as self curing compounds which reduces the water curing, but the results of such products are not very conducive. 3.5k Views · View 1 Upvoter · Answer requested by

Self-Compacting concrete is a type of concrete that gets compacted under its self-weight. It's commonly It's commonly abbreviated as SCC and defined as the concrete which can placed and compacted into every corner of a formwork; purely
The presence of some substances in concrete, including useful and unwanted additives, can cause health concerns due to toxicity and radioactivity. Fresh concrete (before curing is complete) is highly alkaline and must be handled with proper protective equipment.
LaHabra offers acrylic finishes in a base and LaHabra offers acrylic finishes in a base and liquid color system. The LaHabra liquid color is a prepackaged bottle of liquid color composed of pigments and dispersing agents to be mixed into acrylic stucco finishes.

A progression of solid blends were readied and sodden cured for 0, 0.5, 1 or 3 days, or by utilizing a curing compound ...
Admixtures are added to concrete batch immediately before or during mixing concrete. Concrete admixtures can improve concrete quality, manageability, acceleration or retardation of setting time among other properties that could be altered to get specific results.

Different types of chemical admixtures with information on additives that can be added to concete to control air content, water content, corrosion, shrinkage control, alkali-silica reactivity, and coloring.
Self-consolidating concrete is a highly flowable type of concrete that spreads into the form without the need for mechanical vibration. Self-compacting concrete is a non-segregating concrete that is placed by means of its own weight.

Self-curing agent is the essential component for self-curing concrete. It serves as an internal water reservoir with high water absorption capacity in aqueous solution and desorption rate under pressure.
Self-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until ...
Some specific water-soluble chemicals added during the mixing can reduce water evaporation from and within the set concrete, making it 'self-curing.' The chemicals should have abilities to reduce evaporation from solution and to improve water retention in ordinary Portland cement matrix.
