摘要
板岩在我国分布较广,由于具有较高的碱活性及碱活性的特性,作为混凝土的骨料在土木工程中应用的工程还很少。为促进板岩骨料的应用,其碱活性的评定方法尤为重要。目前我国各部门对碱活性的评定标准不统一,为碱活性的检验和判定带来困难。本文对国内标准关于碱活性的评定方法进行了探讨和分析,提出贵州板岩的碱活性的评定方法的建议。
Slate widely distributed in China,due to high alkali reactivity of alkali reactivity and characteristics as concrete aggregate in civil engineering application is little,To promote the application of slate aggregate,The alkali method of assessing the activity is particularly important.At present,our various departments of the alkali reactivity of assessment standards are not uniform,so it is difficult to determine the alkali reactivity tests.The description of this paper will discuss and analyze the standard on the base of the domestic activity of the assessment methods,so that proposing recommendations to the Guizhou slate method ofassessing the activity of alkaline.
