A new mix proportion method of no-fine lightweight brick was investigated based on the blaine of aggregate and thickness of mortar that bonding on the aggregate. The property changing of lightweight brick is studied with varied parameters, such as the thickness, strength, and volume content of mortar except for the fly ash substituted for natural sand. The lightweight brick with unit weight approximately 500kg/m3 and thermal conductivity near 0.15kcal/℃ was manufactured on the basis of the proportioning method. As the volume content of motar approximate to 0.35m3/m3, the compressive strength and the thermal conductivity of lightweight brick is in optimum situation. Otherwise, replace natural sand with fly ash decreases the thermal conductivity of lightweight brick. The principal factor of controlling the lightweight brick strength is aggregate strength. The lightweight brick strength is almost unaffected by the strength of mortar. But when considering viscosity, the volume content of cement should not less than the half of nature sand content. The unit weight prediction formula of lightweight brick is proved to be acceptable.
