Abstract: The coupled heat transportation process of 240mm×115mm×90mm（length × width × height）fly-ash small-sized hollow block with 24 kinds of configurations with different hole number and arrays was simulated, and equivalent thermal conductivity (ETC) of single hollow block was obtained. Heat transfer along length and width direction of the hollow block is considered in the simulation. The results show that with the increase of the holes number in vertical direction of heat transfer, the effect of thermal insulation on hollow blocks is weakened, but with the increase of the holes number in parallel direction of heat transfer, the effect of thermal insulation on hollow blocks is enhanced. The results of three kinds of methods of bricklaying with trowel on masonry units are compared, which helps to pick out the optimal solution. This method can not only reduce the workload and time to find the optimal groove, but the result using new method is better than that of using the conventional method.
