Expansive Cements Expansive Cements I ntroduction Expansive cements are hydraulic cements which, unlike portland cement, expand during the early hydration period after setting. An expansive cement is a cement that when mixed with water produces a paste that after setting increases in volume to a greater degree than does portland-cement paste. This type of cement has been developed by using an expansive agent and stabilizer. The Advantage of High Range Expansive Mortar. Alternative names are "aluminous cement", "high-alumina cement" and "Ciment fondu" in French. The main aluminate phase that is responsible for the formation of ettringitevaries with the cement type. 5.

It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly.... As requirements for demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned.High Range Expansive Mortar is a very good solution. The calcium aluminate cement CAC 40 was ground together with special sulfate–lime sinter to produce an expansive additive to Portland cement (CEM I 42.5R). applications is cheaper than Portland cement and other (expansive) chemical stabilization. A maximum circumferential expansion of 308 μϵ and triaxial compressive stress of 3.65 MPa at 24 h could be obtained, which compacted the core UHPC and improved the interfacial bond between the steel tube and the UHPC.
