Existing, the requirement of mechanical property and durability to concrete structure is also higher and higher, it is achieved that concrete material is more high-strength
Degree, more preferable durability, are the great demands of national stable development.
Ultra-high performance concrete (Ultra-high Perforrmanc Concrete, abbreviation UHPC) is a kind of water-cement ratio
New Building Materials more than low (< 0.2), ultra-fine admixture have superhigh intensity (> 150MPa), high tenacity, excellent durability
The characteristics of can satisfy the high performance requirements of Super High, Ultra-Long Spans and harsh environment flowering structure, be more applicable for harsh
Building structure under marine environment.However UHPC glue material usage amount is big (about 1000kg/m3), is a kind of biggish cement base of energy consumption
Material, it is at high cost, energy consumption is high also become hinder UHPC promote and apply principal element.Pass through the similar auxiliary gelling material of partial size
It is the weight for producing environmental protection UHPC that the supplementary cementitious materials such as feed powder coal ash, miberal powder and agstone, which replace part of cement to prepare UHPC,
Want approach.But the construction of engineering in the offshore generally all take off farther out, freshwater resources and material substance are relatively deficient, use
When traditional building material is constructed, raw material need greatly to increase by remote sea transport the construction of engineering at
This, or even influence the construction efficiency of engineering.
