Description

강도증진용 혼화제, 이를 이용한 콘크리트조성물 및 시멘트모르타르 조성물{ADMIXTURES, CONCRETE COMPOSITION AND CEMENT MORTAR COMPOSITION USING THEREOF}Strengthening admixture, concrete composition and cement mortar composition using same {ADMIXTURES, CONCRETE COMPOSITION AND CEMENT MORTAR COMPOSITION USING THEREOF}

본 발명은 콘크리트조성물 또는 시멘트모르타르조성물의 조기강도를 증가시키고, 균열을 저감하며, 내구성을 증진시키기 위한 강도증진용 혼화제에 관한 것이다.The present invention relates to a strength increasing admixture for increasing the early strength of the concrete composition or cement mortar composition, reducing cracks, and enhancing durability.

콘크리트 또는 시멘트모르타르 등과 같은 시멘트 조성물은 시멘트와 물과의 반응으로 경화되는 수경성 반응물로, 물의 사용량에 따라서 경화 후 압축강도 등의 물리적 특성이 다르다. 보통 물의 사용량의 증가는 작업성을 향상시키는 반면에 압축강도 등을 저하시키고 균열 발생을 초래하므로 시멘트 조성물에 대한 물의 사용량은 제한되며, 물의 사용량을 줄이기 위하여 한국공업규격 KS F 2560에 기재된 바에 따르고, 후술하는 바와 같이 콘크리트용 화학 혼화제를 사용하고 있다.Cement compositions such as concrete or cement mortar are hydraulic reactants that are cured by the reaction between cement and water, and have different physical properties such as compressive strength after curing depending on the amount of water used. In general, an increase in the amount of water used improves workability, while lowering compressive strength and causing cracks, so that the amount of water used for the cement composition is limited, and according to Korean Industrial Standard KS F 2560 to reduce the amount of water used. As will be described later, a chemical admixture for concrete is used.

화학적으로 합성된 혼화제의 종류는 크게 AE제(air entraining admixture), 감수제(water reducing admixture), 고성능 감수제(high range water reducing admixture)등이 사용되고 있다. 또한 시멘트 조성물에 사용되어 미세 공기량을 증가시키는 화학 혼화제인 AE제는 감수제 또는 고성능 감수제와 혼합되어 AE 감수제(air entraining and water reducing admixture) 및 고성능 AE 감수제로 분류되어 있다. AE 감수제의 물을 감소시키는 능력은 사용하지 않는 것에 대하여 물의 사용량을 10 중량% 정도를 감소시킬 수 있으며, 고성능 AE 감수제는 18 중량% 이상을 감소시킬 수 있다.Chemically synthesized types of admixtures include AE (air entraining admixture), water reducing admixture, and high range water reducing admixture. In addition, AE, which is a chemical admixture used in cement compositions to increase the amount of fine air, is mixed with a water reducing agent or a high performance water reducing agent and classified into an air entraining and water reducing admixture and a high performance AE water reducing agent. The ability of the AE water reducing agent to reduce water can reduce water usage by as much as 10% by weight, while the high performance AE water reducing agent can reduce by more than 18% by weight.

근래에 들어서는 높은 감수성과 충분한 유동성을 나타내며 또한, 응결 시간 단축을 통해 조기에 강도를 발현시켜 높은 작업성과 공사 기간 단축을 가능하게 해주는 시멘트 혼화제가 개발되어 왔다. In recent years, cement admixtures have been developed that exhibit high susceptibility and sufficient fluidity, and also exhibit high strength through shortening of condensation time, thereby enabling high workability and shortening construction period.
