NOVELTY - Flexible agent comprises 20-40 pts. wt. modified waste rubber powder , 10-20 pts. wt.expanded vermiculite powder, 10-20 pts. wt. foam concrete waste, 1-3 pts. wt. modified hyperbranched polyethyleneimine, 5-9 pts. wt.amino graft modified graphene oxide, 5-10 pts. wt. magnesium aluminum silicate, 0.5-1.5 pts. wt. polycarboxylic acid water reducing agent, 2-4 pts. wt. EDTA, 4-6 pts. hydroxyethyl cellulose ether, 5-10 pts. wt. zeolite powder and 10-20 pts. wt. papermaking sludge ash. USE - The flexible agent is useful for modifying concrete in concrete pavement. ADVANTAGE - The method: is simple and easy to obtain; makes full use of the binding force between modified waste rubber powder and other materials; ensures the crack resistance, flexural resistance and bonding strength of concrete; and improves the overall flexibility of the concrete system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a flexible agent.
