Title: Interlocking block for pavement
Inventor: HATTORI KEIJI
IPC: C04B28/04
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain a high strength interlocking block while saving natural resources and conserving environmental conditions by constituting the block of course aggregate and fine silica sand and mixing a specified quantity of fine silica sand having a specified range of size distribution therein. SOLUTION: The strength of this block is enhanced by use of fine silica sand and industrial waste fine silica sand is effectively used. In the case that silica sand is too fine, it causes deterioration of strength because cement paste is diluted and in the case that it is course, it can be used for raw of glass and hence, it is not industrial waste. Therefore, fine silica sand of 30-100 μm in particle size is used for the block, in industrial sludge generated in the refining process of silica sand in order to recover a raw of glass. Fine silica sand of 10-30 wt.% to cement, water, and course aggregate such as gravel or crushed stones is mixed with them. Accordingly, natural resources can be saved and environment is conserved and further, a high strength interlocking block can be obtained.
