Title: Repairing method of crack of concrete construction
Inventor: OHAMA YOSHIHIKO
IPC: C04B40/06
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To rapidly repair a crack of a concrete construction by mixing a repairing agent carrier consisting of lightweight aggregates including epoxy resin in concrete before curing at the time of execution. SOLUTION: Eepairing capsules 1 consisting of lightweight aggregate including deeply sufficiently a repairing agent of epoxy resin is mixed as aggregates so as to obtain ready-mixed concrete. When cracks are generated in a concrete construction containing repairing capsules 1, to be caused by drying contraction, stresses are applied to the capsules 1 in concrete, so that the capsules 1 break or crushe to produce cracks. Then, the epoxy resin 2 flows out from the capsules 1, and spreads all over fine cracks, which cures in reaction with a cement hydrant in the concrete to repair cracked parts strongly. Since lightweight aggregates are utilized in a repairing agent carrier, its adhering property with concrete is improved, and they tend to break following cracks and repairing can be done surely rapidly.

IPC: C07C2/66
Filed: 1994-12-22
Abstract: PURPOSE: To industrially and advantageously obtain a p-dialkylbenzene by reacting benzene and/or a monoalkylbenzene with an alkylating agent divided in many stages by using a pentasil type zeolite-based catalyst. CONSTITUTION: Benzene or a monoalkylbenzene or both are reacted with an alkylating agent (propylene is especially preferred) in the presence of a pentasil type zeolite-based catalyst to afford a p-dialkylbenzene. In the reaction, a fixed bed flow method is usually used and the reactional temperature is 180-250 deg.C. The alkylating agent is used in a molar amount of 0.03-0.5 based on the raw material. The alkylating agent is preferably divided into plural stages, preferably 2-4 portions for reaction. When, e.g. the fixed bed reactor is used and the alkylating agent is bisected for reaction, it is fed from a part near an inlet for the catalyst layer and a part near the central part and reacted. The conversion rate can be improved without deteriorating the p-selectivity by simple operations to divide the alkylating agent and reacted in the multistages according to the method.
