【摘要】 通过对透水性混凝土材料进行试验,讨论了影响透水性混凝土材料强度和透水性的因素,认为水灰比、集灰比、粗骨料级配和矿物掺合料的种类是影响其强度和透水性的主要因素。根据试验推荐的原材料、配比和试验方法,可以得到强度达到30MPa,渗透性在1mm/s的透水性混凝土。更多还原

【Abstract】 The experimental study on the porous concrete was carried out,and the fluencial factors on strength and permeability was discussed. Water binder ratio,aggregate binder ratio,aggregate garding,mineral admixture were the main factors. The results show that a compressie strength of 30 MPa,and the water permeability of 1 mm/s can be obtained.更多还原
