The permeability coefficient was in accordance with JCI Eco Concrete Research Committee [Permeability Test Method of Porous Concrete] and the head head difference was 12.5cm. The abrasion resistance test was performed by putting 30 kg of dry sand of 0.3 to 5mm and 6 steel balls (weight 438g) of 47.5mm in diameter into a Los Angels tester for aggregate test. After putting the drum into the drum 30 times to 30 to 33 times per minute, the weight of the specimen was measured to determine the weight loss.
휨강도시험결과 플라이애시를 치환한 경우의 휨강도는 치환율이 증가함에 따라 다소 저하하는 경향을 보이고 있으나 치환율 30%이내에서는 목표치를 만족시키고 있다. 또한 고로슬래그 잔골재는 이번 시험범위내에서는 휨강도의 저하가 확인되지는 않았다. 투수계수 공극률이 15%정도에서는 치환율과는 관계없이 기준항목을만족하며, 마모시험 결과 치환율이 증가함에 따라 손실율이 증가하였으나 20%정도의 치환율에서는 기준치를 만족하는 것으로 나타났으며, 병용한 경우에서는 산업부산물을 첨가하지 않은 경우에는 동등한 물성을 만족하는 플라이애시 치환율을 20%로 고정하여 고로슬래그 잔골재의 치환율이 20%이내에서는 각 기준값을 만족하는 결과를 나타내고 있다. 포장용콘크리트의 내구성을 평가하기 위한 목적으로 기층투수성콘크리트의 휨파괴 시험을 실시하였다. 공시체는 10×10×50cm, 재하방법은 상한하중을 휨강도비(응력비)를 60% 및 70%로 하여 정현파 5Hz 3등분점 방법으로 하였다. 또한 공용시의 간극수의 영향을 고려하여 함수상태의 공시체를 비닐필름으로 피복한 상태에서 시험을 행하였다. 공시체 3개의 파괴회수(파단회수)의 평균을 파괴수명으로 하였을 때 공시체의 파괴회수는 응력비 60%에서는 공시체 3개 모두 200만회에서 파괴되었으며, 응력비 70%의 공시체는 2개가 120만회에서, 1개는 160만회에서 파괴되는 결과를 보이고 있다. 기층침투성 콘크리트의 파괴수명은 같은 시험조건으로 실시한 포장용포러스콘크리트공통시험에 의한 통상의 포장용콘크리트에 비해 동등 이상의 결과를 나타내었다.As a result of the flexural strength test, the flexural strength of the fly ash substituted tended to decrease as the substitution rate increased, but the target value was satisfied within 30% of the substitution rate. In addition, the blast furnace slag fine aggregate was not found to decrease the flexural strength within this test range. The permeability coefficient was about 15%, which satisfies the criterion regardless of the substitution rate, and the wear test showed that the loss rate increased with the increase of the substitution rate. When the industrial by-product is not added, the fly ash substitution rate that satisfies the equivalent physical properties is fixed to 20%, and the replacement rate of the blast furnace slag fine aggregate is within 20%, which satisfies each reference value. For the purpose of evaluating the durability of paving concrete, the flexural failure test of the base permeable concrete was conducted. The specimens were 10 × 10 × 50cm, and the loading method was the sine wave 5Hz third point method with the upper limit load being 60% and 70% of flexural strength ratio (stress ratio). In addition, the test was carried out in a state in which the water-containing specimen was coated with a vinyl film in consideration of the influence of the gap number in common use. When the average number of fractures (breakages) of three specimens was used as the failure life, the specimens were destroyed at 2 million times in all specimens at a stress ratio of 60%, and two specimens at 1.2 million, one at a stress ratio of 70%. Has been destroyed at 1.6 million times. Fracture life of the base-permeable concrete showed more than equivalent results for ordinary pavement concrete under the same test conditions for pavement concrete.
골재비산저항성, 내마모성등의 노면 공용성을 평가하기 위한 목적으로 현장채취한 공시체를 이용하여 마모시험, 회전휠트랙킹시험, 왕복체인라벨링시험 시험을 하였다.Abrasion test, rotary wheel tracking test, and reciprocating in-vehicle labeling test were conducted using specimens collected on-site for the purpose of evaluating the road commonality such as aggregate scattering resistance and abrasion resistance.
여기에서 채취한 공시체의 골재비산 저항성 결과를 살펴보면, 투수성콘크리트 포장의 공용성능은 배수성아스콘 포장과 비교하여 동등이상의 우수한 결과를 나타내고 있어 산업부산물의 유효활용 및 환경을 배려한 광범위한 적용이 가능한 것이다.Looking at the results of the aggregate scattering resistance of the specimens collected here, the common performance of the water-permeable concrete pavement showed the same or better results compared to the drainable ascon pavement, it is possible to apply a wide range of applications by considering the effective use of industrial by-products and the environment.
