Title:
セメントモルタル組成物及びコンクリート組成物
Document Type and Number:
Japanese Patent JP2007537966
Kind Code:
A
Abstract:
The present invention provides a cement mortar composition and concrete composition and particularly, it provides a cement mortar composition comprising 100 parts by weight of cements, 100 to 300 parts by weight of glass beads, and 50 to 200 parts by weight of blending water and a concrete composition comprising the cement composition and aggregates. The cement mortar composition and concrete composition of the invention have excellent fluidity with the use of a small amount of blending water so that they can promptly migrate in the direction of gravity in a mold complicated with steel rods and other wires, prevent material separation and remove bubbles present inner or outer areas due to superior filling performance, can remarkably improve waterproof property of mortar (or concrete) and prevent their degradation. Besides, they require no additional cooling systems which are installed to control heat of hydration in civil engineering such as dams, piers and tunnels that are largely cast by absorbing the generated hydration heat within the mortar (or concrete), show no material separation phenomena, can block the alteration of a structure generated by corrosion by converting the surface of reinforcing rods into passevation, and enable high quality by having a reduced construction period due to shortened time to gain initial hardness from the start of construction, and having the high smoothness of finished faces and having no unevenness such as bubbles due to excellent filling performance.
