发明名称 MOULDING SAND FOR MANUFACTURING BUILDING BLOCKS
摘要 <p>The invention can be employed in construction. Raw materials mixture contains cohesive substance, woodchips, water and differs in that the cohesive substance is bituminous shale ashes and clay at a ratio of 0.3-2.0 from mass percents and mixture components ratio in percents is:clay-20.7/50.4bituminous shale ashes-12.5/46.3woodchips-10.3/26.9water-the rest.The invention gives a chance to acquire hardened non-torpid mixtures for wall block production which has sufficient thermo-technical properties using woodchips (also wood-processing waste) and easy accessible and cheap cohesive substance.</p>
