ON THE RECENT STUDIES AND APPLICATIONS IN JAPAN CONCERNED TO ADMIXTURES IN USE OF BUILDING CONCRETES AND MORTARS. PART 1. EFFECT OF SURFACE ACTIVE AGENTS UPON FRESH CONCRETE AND MORTARS. PART 2. EFFECTS OF SURFACE ACTIVE AGENTS UPON HARDENED CONCRETES AND MORTARS

TWO TOPICS ARE DESCRIBED HERE: (1) RELATION BETWEEN PROPERTIES OF VARIOUS SURFACE ACTIVE AGENTS AND PROPERTIES OF CONCRETE USING THEM, AND (2) RELATION BETWEEN ASSORTMENT OF CEMENT USED AND EFFECT OF SURFACE ACTIVE AGENT UPON PROPERTIES OF CEMENT PASTE AND MORTAR. EFFECTS OF SURFACE ACTIVE AGENTS UPON THE PROPERTIES OF HARDENED CONCRETE: (1) ON RATE OF RESISTANCE TO NEUTRALIZATION (CARBONATION) OF CONCRETE USING SURFACE ACTIVE AGENTS, AND (2) RELATION BETWEEN THE DISTRIBUTION OF ENTRAINED AIR BUBBLE SIZE CREATED IN CONCRETE USING SURFACE ACTIVE AGENT AND DURABILITY OF THE HARDENED CONCRETE. /CRIC/FESR/RRL/A/
