Preparation and Characteristics of Light Foam Cement
This present paper took ordinary Portland cement as main raw materials to prepare foam cement with properties, such as lightweight, high strength, and heat preservation, by the method of chemical foaming. The authors discussed the effects on the properties by key factors like water/cement ratio, foaming agents, foam stabilizers, accelerator and fibers of foam cement objects. Taken all the results show that in the condition that water/cement ratio of 0.48, foaming agents, foam stabilizers, accelerators and polypropylene fibers were adopted accounting for the quality of cement of 4.8%, 0.6%, 0.25% and 0.4% respectively, the characteristics of prepared formed cement samples could conform to the requirement of standard of JC/T266 formed cement.
