一、据东德公路杂志第九期报导,目前国外铺筑混凝土路面多采用含稀释剂的混凝土,如东德采用的路用混凝土是按标准TGL16237/01滲入高强度粘稠剂和加气剂组成的。采用稠度V_3和V_5、塌落度55—60cm的新拌混凝土,其水灰比值为≤0.42或运用加气材料时为0.45,能使新拌混凝土稀释。粘 According to the Ninth National Highway Journal Magazine reported that the current use of paving concrete pavement more than abroad with concrete, such as road use by East Germany is based on the standard TGL16237 / 01 infiltration of high-strength viscous agent and air entraining agent consist of. Fresh concrete with a slump of 55-60 cm, with a consistency of V_3 and V_5, with a water-cement ratio of ≤0.42 or 0.45 with aerated material, allows the fresh concrete to be diluted. stick
