At ICF Concrete Additives we pride ourselves on being the concrete additive resource for high performance products to the concrete industry. Our goal is to promote technologically and economically superior solutions by using our test proven product line and engineering expertise.
Admixtures can restore loads of concrete that might need to be rejected due to delays or other complications. They can improve the performance of problem concrete by modifying its characteristics and enhancing workability. Admixtures are additions to a concrete mix that can help control the set time and other aspects of fresh concrete.
The Research on the Additives of the High Performance Concrete Chai Ziqin*, *(School of Civil Engineering, Chongqing Jiaotong University, Chongqing 400074,China ABSTRACT With the development of technologies of admixture and additive in concrete,the technological base for making up high performance concrete has been laid.
The composition of high performance concrete (HPC) are almost same as those of Conventional Cement Concretes( CCC ). But, because of lower Water Cement Ratio, presence of Pozzolans and chemical admixtures etc., the HPCs usually have many features which distinguish them from CCCs.
On the other side, chemical additive industry growth will be driven by increasing plasticizers and water reducers demand in high performance and self consolidation concrete (SCC) areas. Application segment includes residential, industrial, commercial, and others.
self-compacting concrete and high performance self-compacting concrete. HCFA was used as an additive for concrete (up to 30%) or as a main constituent in cement. Studies have confirmed the possibility of HCFA use in self-compacting concrete, while maintaining the assumed workability of fresh concrete
Now a day's high performance concrete is globally used in the infrastructure industry for strong and durable structure, to produced high performance concrete various supplementary cementitious material are used as mineral admixture. This research
Mineral admixtures make mixtures more economical, reduce permeability, increase strength, and influence other concrete properties. Mineral admixtures affect the nature of the hardened concrete through hydraulic or pozzolanic activity.
Our customers will benefit by having access to a broader portfolio that includes halloysite clay, a high-performance mineral additive, and our line of high-quality kaolin .
For example, Self- compacting Concrete is a specific part of High Performance Concrete, which distinguishes itself with self-consolidation properties coupled with high flowability. Table 1 shows the Properties and Areas of application of High Performance Concretes. Table 1a shows some properties and areas of Application of HPCs.

The application of perlite microspheres in foam concrete was investigated. The thermal conductivity coefficient was defined by rapid method. The optimal composition of the mixture for manufacturing foam concrete products with mineral additives ensures the decrease in the heat conductivity coefficient by 41-43% compared to the reference composition.
high-performance concrete and why they are selected. Table 17-2 lists properties that can be selected for high-performance con-crete. Not all properties can be achieved at the same time. High-performance concrete specifications ideally should be perform-ance oriented. Unfortunately, many speci-fications are a combination of performance
Use of mineral additives in concrete formulations is expanding due to efforts to reduce overall cement consumption and to take advantage of performance attributes offered by industrial waste .
Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) is a relatively new construction material, which is a combination of high performance concrete and fibre reinforcement. The compressive strength reaches beyond 150 MPa, which allows the construction of sustainable and economic buildings with an extraordinarily slim design.

Keywords – deterioration, high performance concrete, mineral admixtures I. Introduction High-performance concrete is defined as concrete that meets special performance and uniformity requirements that cannot always be achieved routinely by using conventional materials and normal mixing, placing, and curing practices.
Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio. This usually indicates that a higher strength concrete can be produced without increasing the amount of cement.
Jun 11, 2010 · High performance concrete is a concrete mixture, which possess high durability and high strength when compared to conventional concrete. This concrete contains one or more of cementious materials such as fly ash, Silica fume or ground granulated blast furnace slag and usually a super plasticizer.
Over decades, attempts have been made to obtain concrete with certain desired characteristics such as high compressive strength, high workability, and high performance and durability parameters to meet the requirement of complexity of modern structures. The properties commonly modified are the heat of hydration, accelerate or retard setting .
