High strength lightweight mortar composition comprising pre-wetted artificial lightweight fine aggregate with recycled water of ready mixed concrete
The present invention relates to a high strength lightweight mortar composition which is formed by including artificial light weight fine aggregate pre-wetted with ready-mixed concrete recovery water. The high strength lightweight mortar composition is formed by mixing 140-180 kg/m^3 of mixed water, 320-450 kg/m^3 of cement, 500-700 kg/m^3 of artificial light weight fine aggregate, and 35-45 wt% of water cement. The artificial light weight fine aggregate is manufactured by mixing and plasticizing fly ash and dredged soil. The high strength lightweight mortar composition has a particle diameter less than 5 mm, more than 80 wt% of the sum content of SiO_2 and Al_2O_3, and density less than 1.8 g/cm^3. The high strength lightweight mortar composition is formed by pre-wetting contents in ready-mixed concrete recovery water for 22-26 hours, and adjusting the contents in a surface dried state to mix the contents.
본 발명은 레미콘 회수수로 프리웨팅(pre-wetting) 처리한 인공경량잔골재를 포함시켜 조성하는 고강도 경량 모르타르 조성물에 관한 것이다. 본 발명은 「배합수 140~180kg/㎥, 시멘트 320~450kg/㎥ 및 인공경량잔골재 500~700kg/㎥, 물시멘트비 35~45wt%%로 배합되되, 상기 인공경량잔골재는 석탄회와 준설토를 혼합 및 소성하여 제조한 것으로서, 입경 5㎜ 미만, SiO2와 Al2O3의 합산 함량 80wt% 초과, 밀도 1.8g/㎤ 미만이며, 레미콘 회수수에 22~26시간 동안 프리웨팅(pre-wetting)시킨 후 표건상태로 조정하여 혼합한 것을 특징으로 하는 고강도 경량 모르타르 조성물」을 제공한다.
