        Influence Factors of Foam Concrete Block
        2016/4/5

        1. Density is an important index to measure the quality of the foam concrete. The density of the foam concrete is mainly depends on these factors, such as vesicant content and water content, etc. The density of lightweight foam concrete is generally 300-100kg/m3, while the density of normal concrete is 1900-2500kg/m3.

        2. Compressive strengththe strength of lightweight concrete block is generally 2.0 mpa, 2.5 mpa, 3.0 mpa, 3.5 mpa, etc. The foamed block which achieved the strength can be used to make the non-load bearing wall.

        3. Thermal conductivity: Compared with ordinary concrete, foamed concrete has excellent thermal insulation(0.05kcal/m°C). Its thermal insulation is about 20~30 times of the ordinary concrete, so foamed concrete has a strong insulation.

        Note: The data all above vary from the allocation condition of work-site. (The data is only provided for your reference by our company.)
