稻壳混凝土热学与力学特性试验研究

Experimental study on thermal and mechanical characteristics of rice husk concrete

研究稻壳混凝土的导热系数和不同的稻壳耦合剂对稻壳混凝土强度影响规律。试验表明:掺入稻壳后,混凝土的导热系数有大幅度的降低,约为普通混凝土导热系数的14%～20%;随着稻壳耦合剂每增加10%时其稻壳混凝土的强度也随着增加5%～20%,从而表明稻壳耦合剂在改善稻壳混凝土的黏结性能方面起着很大的作用。

The thermal conductivity office husk concrete and the influence rule on amount office husk coupling to the intension of concretes are researched furtherly.Experiments show that, as the incorporation of rice husk, the thermal conductivity of concrete which is substantially lower than the ordinary concrete is about 14% to 20% ;as increasing the 10% office husk coupling,the concrete strength is also increased from 5% to 20%.Rice husk coupling plays a significant role in improving the bonding properties office husk concrete.
