Abstract
This paper proposes an absolutely new mixing procedure for improving resistance to freezing and thawing as well as workability by enveloping the lightweight coarse aggregate with cement paste, and compares experimentally the new mixing procedure with the conventional one on consistency, compressive strength and resistance to freezing and thawing (as per ASTM C 666 Method A) of the respective high-strength light-weight concrete of the same mix proportion mixed by both procedures. The results of these tests show that the new mixing procedure will greatly improve consistensy and resistance to freezing and thawing.
