摘要 PURPOSE: To obtain an economical centrifugal compaction concrete and mortar by mixing fine grains into a centrifugal compaction concrete and mortar and increasing compression strength and/or decreasing an amount of binding material used.
CONSTITUTION: A kneaded material which is a material for subjecting a cement secondary product consisting of concrete and cement to centrifugal compaction forming is prepared. Then inorganic or metallic fine grains having smaller gravity and/or specific gravity than those of belended binding material is blend ed into the kneaded material at a ratio of ≤ 200 kg/m
2 , preferably about 60kg/m
2 . The fine grains include e.g. fine grains of coal lime, blast furnace slag and fumed silica. Thus, compression strength of concrete is increased and/or an amount of binding material used is creased and a more economical centrifu gal compaction concrete and mortar are obtained by blending the above- mentioned fine grains into the centrifugal compaction concrete and mortar.
