| PURPOSE: To obtain an action to increase the binding strength of cement and prevent snow from sticking to a power transmission line by allowing an ionic crystallizing ceramic to remain for a long time under an electric field which converts its direction alternately at a constant high voltage. CONSTITUTION: An ionic crystallizing ceramic component is allowed to remain, for example, in an area which is acted upon by an electric field changing its direction alternately at high voltage of 30000V, for 8000 hours or longer. Consequently, the influence by the alternating effect settles and a secondary structural feature which is different from an initial structural feature is obtained. Further, other effects such as increasing the binding strength of cement and preventing snow from sticking to a power transmission line are obtained. COPYRIGHT: (C)1994,JPO&Japio | ||||||

| 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.
