Evaluation and Development of Material to Improve for Concrete Surface

Abstract

I assume it the low water cement ratio to improve the durebility of a concrete makeup,and it is the most common I am minute,and to grind an organization.However,I may produce different problems such as a cost,the self-shrincage,hydration fever to apply to execution of a true makeup,and difficulty is accompanied with an application concrete surface reforming materials(following reforming materials) attract attention from this recently.An ingredient seeps from the surface inside by applying it to the concrete surface,and this gives a new function to the concrete outer layer region or an inner deep part,and can improve the durability of concrete and materials aimed at letting a concrete original function recover is because is it.Generally concrete produces weathering deterioration by outdoor combination of a long term,and the durability of the paula concrete organization which became it falls by the weathering.Therefore the writers paid their attention to deterioration by elution of cement generation thing,the neutrality by carbon dioxide among this weathering deterioration and carried out an application experiment of reforming materials about main performance and permeability,water absorptivity of elution deterioration and the neutraliity of carbin dioxide deterioration.I report the examination result here.
