This study relates to retardation effects of some inorganic compounds on a set of cement mortar. Zinc oxide, Basic zinc carbonate, Copper（Ⅰ）oxide, Copper（Ⅱ）oxide and Basic copper carbonate were used as an inorganic set retarder. Additionally, mixtures of those compounds were tested to examine a combination effect. It was found that retardation effect of zinc compounds was bigger than that of copper compounds. The difference of retardation effect between the zinc compounds was small. And the difference of retardation effect between the copper compounds was also small. Using basic copper oxide and zinc oxide together made the retardation effect bigger than single use of zinc oxide or basic copper carbonate. Particularly, in the case of using a mixture of zinc oxide and basic copper oxide in the ratio of 2：1 by mass, setting of mortar was retarded up to about 10th day. Remixing the mortar shortened the set time, that is to say, decreased the retardation effect. Compressive strength of the mortar at the 28th day was comparable to that of plain mortar. It means those retarders do not affect on the compressive strength at such an age.

Low-heat Portland blast furnace slag cement is the cement which raised a ratio of the ground granulated blast furnace slag and reduced the specific surface area of cement by blaine. When Portland blast furnace slag cement is used by binder, the temperature rise of concrete is lower than that of using ordinary Portland cement. In the case that low-heat Portland blast furnace slag cement is used by binder, the temperature rise of concrete is more low that of using Portland blast furnace slag cement which the specific surface area of cement by blaine is high. In the case of using Portland blast-furnace slag cement which raised a ratio of the ground granulated blast furnace slag, compressive strength and carbonation of concrete are worse than that of using ordinary Portland cement. However, sulfuric acid attack resistance is higher than that of using ordinary Portland cement. And in the case of using blast furnace slag sand together, resistance of sulfuric acid attack is more high. In addition, the drying shrinkage strain of concrete with Portland blast furnace slag cement and blast furnace slag sand is smaller than that of using ordinary Portland cement and crushed sand. And in the case that concrete with Portland blast furnace slag cement and blast furnace slag sand cured in stream, the drying shrinkage strain becomes small more.
