Conventional concrete is a relatively brittle material, while the fibers in concrete construction, in addition to cement, aggregates, water and additives for fibers used in concrete mix, because it has more strength and vitality is to prevent cracking and fiber strands are actively limiting the ...
Tests on prism out of ultra-high-performance fiber reinforced concrete (UHPFRC) were performed in order to further clear up the size effect, i.e. the strength decrease with increasing depth for axial tension and flexure as well as for co... B. Frettlhr,K. -H. Reineck,H. -W. Reinhard...
our products achieve superior strength, workability and enhanced finishing at low water-to-cement ratios. Our offerings include precast solutions, fiber reinforcement, air-entraining agents, water reducers, retarders, accelerators, superplasticizers, corrosion inhibitors, shrinkage reducers, viscosity-modifying...
wollastoniteis a naturally occurring mineral with a high aspect ratio that serves as fiber reinforcement in concrete. Its calcium silicate composition allows it to chemically bond with the cement matrix, providing superior strength and resistance to crack formation...
reported for the steel fiber slabs under similar conditions. Among allfiber types, steel fibers are known to have highermodulus of elasticitythan the concrete matrix which means they can enhance the load-carrying capacity, thus increase the tensile strength of the material. Concrete with steel ...

Influencing factors for fiber functionality As discussed above, the mechanical strength of UHPC can be improved by using fibers. These fibers bridge cracks and transfer stress between fiber and matrix, which capacity of fibers can be determined by bonding properties between fiber and matrix66,67,68...

The test results show that the addition of superplasticizer and fine mineral additives enabled the UHPC to be produced at an extremely low water/binder ratio of 0.14–0.18, achieving excellent workability with a maximum slump of 268 mm and compressive strengths of 175.8 MPa at 90 d and 182.9 ...
inducing cracks, increasing the pore size and total volume, destroying the interface microstructures of aggregates and mortars, then the expansion is harmful for mechanical strength and durability of concrete. Restraints on the expansion facilitate microstructure densification, particularly the paste–...
