Development and application of high performance building materials - Ultra high performance concrete(UHPC)

• Product introduction

UHPC is an ultra-high performance cement-based composite with ultra-high strength (compressive strength ≥ 120MPa, tensile strength ≥ 5MPa), high toughness and high durability

Construction Materials Viscosity reduction technology
Self developed chemical viscosity reducer, viscosity reduction25%
Composite mineral viscosity reducer, viscosity reduction20%
Shaping and friction reduction technology of fully graded aggregate,Further reduce the viscosity of the mixture

High modulus Technology
Self developed high-performance admixture, which maintains good fluidity and no segregation when a large amount of coarse aggregate is added
Optimize the variety, particle size and content of high-strength aggregate to form a series of high modulus products

Ultra high mechanical properties

It has ultra-high compressive strength (compressive strength ≥ 160MPa after curing at room temperature for 28 days), tensile strength and high toughness

Ultra high durability
The matrix is dense, and the internal pore structure is not connected. It has high frost resistance, carbonization resistance, permeability resistance, chloride ion resistance and sulfate resistance

Microcrack self healing
Under the condition of high strain, it still has good self healing ability of microcracks

Low carbon environmental protection
The carbon emission per unit intensity is reduced by 40%, which is energy-saving, material saving, low-carbon and environmental protection
