The properties of super-flowing concrete with low heat cement were experimentally investigated and compared with ordinary 25-240-15 concrete with type Vcement. The cement content of super-flowing concrete with the low heat cement was 400 kg/$\textrm{m}^3$. However the hydration heat of super-flowing concrete is relatively lower than that ordinary concrete with type V cement. Also the ability to resist chloride ion penetration of super-flowing concrete with low heat cement is 5 times better than that of the ordinary concrete.

To analysis the failure character of Low-Heat concrete which is used to prevent the thermal crack caused by hydration heat, static loading test was performed by this test method, "Determination of the Fracture Energy of Motar and Concrete by Means of Three-Point Band Tests on Notched Beam" (suggested by RILEM 50-FMC Committe). This study compared and analysised the fracture energy of Mode I (opening mode), the most general pattern in the view of water-cemente ratio(W/C), compressive strength and age of Ordinary Portland Concrete and Low-Heat Concrete under the same mixture. The test results show that the case of Ordinary Portland Concrete and Low-Heat Concrete, low Water-Cemente ratio(W/C) cause the increase of fracture energy, and high failure-strength decrease failure-deflection, and the fracture energy of Low-Heat Concrete is similar to Ordinary Portland Concrete as the age increase. increase.

In hardening massive concrete, the heat of hydation gives rise to considerable thermal gradientsand thermal stresses, which might cause early age cracking. This paper deals with the results of evaluation of hydration heat of low hear concrete, using Belite rich cement (low heat cement) and compared with OPC, slag added cement and fly ash addedcement. Result of evaluation of hydration are presented in this paper. The concrete made with Belite rich cement gets low temperature of center point and low thermal gradients between surface and center points.

The properties of Low-heat cement are especially in lower heat of hydration than that of other types of cement. In other respect, Low-heat concrete is more advantageous than OPC concrete in chemical resistance, long term age compressive strength, slump loss and resistance to seawater. This paper deals with 28 days age compressive strength and slump loss by elapsed time of mortar and concrete that made with Low-heat cement and 3 types of other cement.

In the case of the offshore concrete structures like the anchorage block of a suspension bridge of Kwangan Grand Road, there is a need of the concrete which has low heat of hydration and good resistance for sea-water attack. In this study, the blended super low heat cement which satisfies that requirement was developed and several tests were carried out. The concrete using the blended super low heat cement showed lower adiabatic temperature rise than 3$0^{\circ}C$ and good early strength. Also, its passed charge(coulomb) to resist chloride ion penetration was very low.

Recently, the crack of concrete induced by the heat of hydration of cement is a serious problem for more greater, special and higher strength of concrete structures. The increasing concrete's temperature is mainly caused by the heat of hydration of cement and so, to control the thermal stress of concrete structure is desirable to use low heater material of hydration. There are many methods to diminish the increasing of concrete temperature such as using of low heat cement, addition of fly-ash, application of pre-cooling, etc., and in this study, we evaluate the heating and mechanical properties of ultra low heat mass concrete using Low Heat Portland(KS Type IV) cement with 30% of limestone powder. The results of this study will be applied to side wall and bottom of No. 15 and 16 of underground LNG tank in Inchon.

본 연구에서는 매스콘크리트의 수화열 저감 및 초기강도 향상을 목적으로 3성분계 배합에 따른 콘크리트의 기초적 특성을 분석하였는데 결과를 요약하면 다음과 같다. 굳지 않은 콘크리트의 물성은 목표범위를 모두 만족하는 것으로 나타났다. 응결시간은 W/B와 관계없이 저열 시멘트 배합이 가장 빠른 것으로 나타났고, 간이 수화열은 저열 배합의 피크 온도가 가장 높은 것으로 나타났고, 저발열-B 배합이 가장 낮은 온도를 나타내었으며, 조강형 저발열 배합은 저발열-B와 유사한 것으로 나타났다. 경화 콘크리트의 압축강도는 초기재령에서 저발열-B 배합을 제외한 모든 배합이 유사한 강도 범위를 나타내었고, 장기 재령에서는 큰 차이 없이 유사한 강도 범위를 나타내었다.

In this study, for the evaluation of field application of low heat concrete using high volume mineral admixture, the characteristics of hydration heat generation and engineering properties of low heat concrete was investigated by mock-up test according to the replacement ratio of mineral admixture. Also, it was evaluated the compressive strength of low heat concrete with curing temperatures and ages for effective concrete mix design considering seasonal change.

In recent years, concrete construction have become larger and higher and are demanding high performance concrete with lower heat to prevent thermal cracking, far greater workability, high strength and durability. Application of low heat portland(Type IV) cement for the high performance concrete is the best solution to satisfied those requirements. Here are explained the basic properties of fresh concrete as well as hardened concrete of high performance concrete using low that portland cement.

Accelerated chloride diffusion tests were carried out to estimate the chloride diffusion coefficient of concrete using ordinary portland cement, low heat belite-rich portland cement, and sulphate resistant portland cement. Concrete using low heat belite-rich portland cement showed a high diffusion coefficient due to delayed hydration of low heat belite rich portland cement, while the diffusion coefficients of concrete using sulphate resistant portland cement and ordinary portland cement were low.
