pumice concrete การใช้

• It is very important to choose a proper mix technology to make pumice concrete
• At last , this article studies the performance of mechanics and durability of those pumice concrete hollow blocks
• Pumice concrete after being close - grained and molding is not sensitive to maintaining conditions , and this idiosyncrasy can predigest maintaining measures and reduce lacuna
• Test result indicates that , by means of using proper gravel - gradation and technology , the performance of pumice concrete can well meet the need of our country wall materials
• Adding air - entrained agent can enhance the heat preservation performance of pumice concrete and improve its durability . using water - reducing admixture can improve the performance of pumice concrete , but the quantum is bigger than in the ordinary concrete
• Secondly , this article uses variance analysis and other research means of statistics to study and definitize the best mix proportion ration of pumice concrete , and studies mechanics and durability of the concrete using the best mix proportion
• Firstly , this paper expounds the research on the physical and chemical performance of pumice and the action of those performance to pumice concrete , and the adaptability of calcium lignosulfonate to pumice concrete , and the influence of air - entrained agent to the performance of pumice concrete
