Abstract：Foam cement is gradually becoming new wall materials due to its excellent performance as energy saving,environmentally friendly and fireproof.The ultra-light insulation materials with its apparent density of 160 kg/m3 and the strength meeting the requirements were prepared by means of chemically foaming method,using the ordinary Portland cement as the binder.The study examine the correlation of stirring conditions,composition of raw materials,curing methods with the mechanical properties of the ultra-light foam cement.The results show that foam cement can own favorable stability,appropriately uniform porosity and excellent mechanical properties by controlling the stirring parameter and the addition of component materials;and curing methods have influence on the compressive strength of foam cement partly:the compressive strength is the highest under natural curing conditions,standard conditions followed;and steam conditions the lowest.
