Description
본 발명은 콘크리트 배합 조성물 및 콘크리트 배합방법에 관한 것으로, 콘크리트의 강도를 증강시키고 동해 방지하는 콘크리트 배합 조성물에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a concrete compounding composition and a concrete compounding method, and more particularly, to a concrete compounding composition for enhancing the strength of concrete and preventing corrosion.
일반적으로, 콘크리트는 시멘트가 물과 반응하여 굳어지는 수화반응을 이용하는 것으로, 최근 들어, 건설 기술의 고기능화로 인해, 건설 재료의 특성이 점차 복잡하고, 다양해지고 있으며, 이에, 고도의 특성을 부여한 건설용 재료의 연구개발이 활발하게 진행되고 있다.
Generally, concrete uses a hydration reaction in which cement reacts with water and hardens. In recent years, the characteristics of construction materials have become increasingly complicated and diversified due to the advanced function of construction technology, and therefore, Research and development of materials for use is being actively pursued.
최근 콘크리트 내에 섬유보강제를 혼입함으로써 콘크리트의 내구성 내지 충격강도 등을 보강하는 다양한 구조의 건설용 콘크리트 구조체 및 투수성을 향상시킨 투수성 콘크리트가 각종 건설 또는 토목 공사에 이용되고 있으나, 상기의 투수성 콘크리트의 경우는 투수성이 향상된 반면, 내구성 충격강도 등이 저하됨에 따라 온도 응력 및 균열 발생을 억제하기 어려운 단점이 있다.
Recently, a construction concrete structure having various structures for reinforcing the durability or impact strength of concrete by incorporating a fiber reinforcing agent into concrete has been used for various construction or civil engineering works. However, The water permeability is improved, but the durability impact strength and the like are lowered, which makes it difficult to suppress the occurrence of temperature stress and cracking.
한국 공개 특허 제 10-2000-0073774호에는 시멘트에 첨가하는 혼화재 조성물에 대해 나타나있다. 상기와 같이 시멘트에 혼화재 조성물을 넣어 콘크리트의 강도를 증강시키기 위한 다양한 방법을 나타내고 있다.
Korean Patent Laid-Open No. 10-2000-0073774 discloses an admixture composition added to cement. Various methods for increasing the strength of the concrete by putting the admixture composition into the cement as described above are shown.
콘크리트의 또 다른 문제로 콘크리트의 공극수가 동결 및 융해를 반복하면서 콘크리트 수화조직을 연약화시켜 내구성이 저하되는 현상이 나타나는데, 이를 콘크리트의 동해라고 한다. 콘크리트의 동해는 공국수가 동결되면서 체적 팽창이 발생하게 되고, 얼었던 물이 녹은 후, 재 동결되면 주변 용존 알칼리의 농도를 증가시켜 체적 팽창이 더욱 가속되고, 동결, 융해의 반복은 골재와 경화 시멘트 박리의 원인이 되는 문제가 있었고, 이에 대한 해결 방안이 시급한 실정이다. Another problem of concrete is that the pore water of concrete repeatedly freezes and melts and weakens the durability of concrete hydrated structure. In the East Sea of concrete, volumetric expansion occurs by freezing of the mainland number. When the frozen water is melted after the frozen water is frozen, the volume expansion of the surrounding alkali is increased to further accelerate the volumetric expansion. There has been a problem that causes peeling, and a solution for this problem is urgent.
본 발명은 콘크리트 배합 조성물 및 콘크리트 배합방법을 제공하는 것을 목적으로 한다.
It is an object of the present invention to provide a concrete compounding composition and a concrete compounding method.

강도 증진 및 동해 방지용인 콘크리트 배합 조성물이 포함된 콘크리트의 압축 강도 비교Comparison of Compressive Strength of Concrete Containing Mixture Composition for Preventing Strength and Antifouling
시멘트는 일반 포트랜드 시멘트 1종을 사용하였고, 포틀랜드 시멘트의 압축강도는 하기 표 1과 같다. Table 1 shows the compressive strength of Portland cement.
제조예 및 비교예 1 내지 7에 의해 제조된 콘크리트의 압축강도를 측정하였고, 그 결과는 하기 표 2와 같다. The compressive strengths of the concrete prepared in Production Examples and Comparative Examples 1 to 7 were measured, and the results are shown in Table 2 below.
상기 표 2에 의하면, 강도 증진 및 동해 방지용인 콘크리트 배합 조성물과 시멘트의 배합 비율에 따라 강도의 차이가 나타났다. 시멘트만 사용한 경우에 비해 콘크리트 배합 조성물을 배합한 경우 일반적으로 강도 증진 효과가 나타났으나, 배합의 비율을 시멘트: 콘크리트 배합 조성물을 180:1 내지 200:1로 배합한 경우 강도 증진 효과가 25% 내지 30%증가되는 것으로 나타났다. According to the above Table 2, there was a difference in the strength depending on the blending ratio of the cement composition and the concrete reinforcing composition for strength enhancement and anti-freeze. Compared with the case where only the cement was used, the reinforcing effect of the concrete composition was generally enhanced. However, when the blending ratio of the cement: concrete composition was from 180: 1 to 200: 1, To 30%.

ⅱ) 4℃ 내지 -8℃의 급속동결 및 융해를 2 내지 4시간에 1회주기로 반복 실시함Ii) Rapid freezing and thawing of 4 ° C to -8 ° C is repeatedly carried out once every 2 to 4 hours
ⅲ) 급속 동결 및 융해를 300회 경과 후 상대 동탄성 계수의 변화를 측정함Iii) Measuring the change in relative dynamic modulus after 300 cycles of rapid freezing and thawing
ⅵ) 상대 동탄성계수란 내동해성을 판정하는 기준으로 탄성재료의 이론상 공명진동수 혹은 파동전파 속도로부터 탄성계수를 구할 수 있다. 불완전탄성체인 콘크리트에 이 방법을 이용하여 동역학적으로 구해진 탄성계수를 동탄성계수라고 한다. Vi) Relative dynamic modulus is a criterion for determination of inferiority, and it is possible to obtain elastic modulus from the theoretical resonance frequency or wave propagation velocity of elastic material. The elastic modulus calculated dynamically using this method for the concrete, which is an incomplete elastomer, is called the dynamic modulus.
동탄성 계수 산정식Dynamic modulus of elasticity formula
Pc = n1 2/n2 Pc = n 1 2 / n 2
(PC는 동결 및 융해의 C회 반복 후의 상대 동탄성계수, n1은 동결 및 융해의 C회 반복 후 1차 진동 주파수, n은 동결 및 융해 전의 1차 진동 주파수)
(PC is the relative dynamic modulus after C cycles of freezing and thawing, n 1 is the primary vibration frequency after C cycles of freezing and thawing, and n is the primary vibration frequency before freezing and thawing)
(2) 내구성 지수(2) Durability index
내구성 지수(Durability factor)란 콘크리트의 내구성을 나타내는 지수로, 동결 및 융해 시험을 끝냈을 때의 상대 동탄성 계수의 값을 의미한다. Durability factor is a measure of the durability of concrete, which means the value of relative dynamic modulus when the freezing and thawing tests are finished.
산정식: Df=P*N/mFormulas: D f = P * N / m
(P는 n회 반복 상대 동탄성계수, N은 정해진 P 동결 및 융해 횟수, M은 정해진 동결 및 융해 횟수)
(Where P is the nth repeated relative dynamic modulus, N is the predetermined number of P freezing and thawing times, M is the predetermined freezing and thawing number)
