STRENGTH OF CONCRETE MADE WITH ANDESITE AGGREGATES

The paper presents and discusses the results of a number of tests in which possible reasons for the increased compressive strength of andesite aggregate concrete were investigated. The tests deal largely with the potential for andesite fines to react with the products of cement hydration, and the potential for cement paste to adhere to the aggregate surface by mechanical interlock. It is concluded that andesite fines do not have a marked potential for reaction with the products of cement hydration and that increased concrete strength is largely due to the physical characteristics of the andesite, such as surface texture, aggregate integrity, and elastic modulus.(a)
