大型堆石混凝土试块特性对比试验研究
Comparative experimental investigation on the properties of large rock-filled concrete test blocks
摘要
Abstract
Rock-filled concrete is a new technology for mass concrete that is developed on the basis of the self-compacting concrete.However,there exist certain uncertainties in the stone sources of rock-fill concrete.Pouring test in the engineering field to investigate the properties of large rock-filled concrete is an important prerequisite for the successful application of this technology,This paper aims to perform a comparative experimental investigation on the properties of large rock-filled concrete test blocks,which are poured by using excavated rocks and local collected pebbles at Wuxikou hydro-junction project site as rock-fills,respectively.The properties of large rock-filled concrete test blocks are studied and compared systematically through the concrete indexes,including compressive strength,permeability coefficient,elastic modulus and carbonization depth of the test block.The superiority and feasibility of taking excavated rocks as the stone sources of rock-fills are verified.关键词
