A lightweight and energy saving mortar consisting of: 30-40% of Ordinary Portland cement; 2-4% of Hydrated lime; 10-20% of lightweight aggregate; 40-50% of heavyweight aggregate; and 1.0% of additive. The lightweight aggregate is a porous inorganic hollow glass material of fineness is smaller than 100 mesh. The heavyweight aggregate is Aeolian sand. During application, the mortar is diluted with water to have a viscosity suitable for mechanical spraying or manual application. The present invention employs a specific lightweight aggregate of porous inorganic hollow glass material to reduce the weight percentage of sand stone so as to decrease the weight of the mortar such that an elastic modulus of the mortar is matched with the lightweight wall object, the heat transmission coefficient is decreased, and the thermal bridge effect is minimized. Hollowing, cracking, and falling off problems are prevented. Heat and sound insulation are improved. Mechanical operation is facilitated.
