Experimental Study And Application To Improve The Strength Of Underwater Concrete Piles

With the development of society, there have been more and more development of coastal waters and lots of underwater engineering, underwater construction structure is complicated, especially in the deep area of sea. Better quality of concrete is required in underwater construction execution of work of concrete, as well as simple technology of construction execution of work, reasonable economy, no pollution. Thus enhancing underwater concrete property was highly valued by engineering groups ,This paper had done tentative research on enhancing underwater concrete filling pile intensity.In order to enhance underwater concrete filling pile intensity, this paper elaborated in detail the components and properties of underwater concrete anti-dispersion agent and mixed fortifier , and took tentative research on their effect on underwater concrete property , analyzed anti-dispersion agent and mixed fortifier mechanism of working ,put forward best mixture values of anti-dispersion agent that was mixed with mixed fortifier in underwater concrete of new type .Through test, effect on underwater concrete filling pile intensity by aggregate quality and interface bond strength was analyzed, put forward the assessing index of choosing aggregate, meantime, still initially researched concrete mixtureration optimum design of underwater filling pile and anti-dispersion agent filling pile technologyThis paper put forword newly researched underwater concrete anti-dispersion agent and mixed fortifier, which was successfully applied in railway guest station's synthetical building foundation engineering execution of work in some city...
