QUICK-HARDENING AND EARLY STRENGTH CONCRETE COMPOSITION MODIFIED WITH ACRYL LATEX OF FLUORINATED COMPOUND AND REPAIRING METHOD OF BRIDGE OR CONCRETE ROAD THEREWITH

摘要

The present invention is an acrylic synthetic latex incorporating a fluorine-based compound to suppress the cracking caused by the temperature deformation and self-shrinkage deformation of the concrete caused by hydration of the cement in the preparation of the superhard and latex latex modified concrete composition It relates to a repair method of a bridge deck plate and a concrete pavement using a super-hard diameter and a crude steel concrete composition. To ^- and more particularly, initial velocity environment and crude Latex Modified reduce the fast and high hydration heat of the concrete and character were to add a fluorine-based compound that can cause an endothermic reaction within the concrete, in the case of the fluorine-based compound in powder form fluoride ion (F) this considerable time is required to transition faster than fluoride (F ^-) for a transition to a fluorine-based compound in liquid form mixed with the manufacture of acrylic synthetic latex was applied to the initial velocity and light crude latex modified concrete. It also relates to a method of repairing bridge decks and concrete pavements using them.
