다국어 초록 (Multilingual Abstract)

This study was carried out to determine the effect of accelerated curing on the strength of briquette-ash adding carbide-ash 10% mortar. The cement:standard sand and the cement:briquette-ash adding carbide-ash 10% at the ratio of 1:2, 1:3 and 1:4, respectively, were cured at 4 different temperature of 20℃, 60℃, 80℃ and 100℃.
The compressive and tensile strength of mortars were measured at σ_3, σ_7, σ_28. The results obtained were summarized as follows;
1. The increasing rate of strength in compression and tension was significantly higher at the mortars of cement and briquette-ash adding carbide-ash 10% than those of cement and standard sand.
2. The enhancement of the mortar strength was still expected by the experimental results that the compressive strength of cement briquette-ash adding carbide-ash 10% mortar showed an increase of 114% by the accelerated curing at 60℃, 136.2% at 80℃, and 164.2% at 100℃ respectively, compared with the compressive strength of mortar cured at 20℃ for each days.
3. The enhancement of the mortar strength was still expected by the experimental results that the tensile strength of cement briquette-ash adding carbide-ash 10% mortar showed an increase of 130.6% by the accelated curing at 60℃, 171.2% at 80℃, and 211.4% at 100℃, respectively, compared with the tensile strength of mortar cured at 20℃ for each days.
4. When the briquette-ash adding carbide-ash 10% was substituted for the materials of cement mortar, decline of the mortar strength was unavoidable. But the cement briquette-ash adding carbide-ash 10% mortar was expected to be increased in strength by the accelerated curing at high temperature.
The cement briquette-ash adding carbide-ash 10% mortar was expected to be utilized to the constructions which need low strength of mortar.
