大量试验表明:粉煤灰水泥混凝土具有和易性好、拌和省时、节约水泥并降低其水化热温升;减少混凝土尚未终凝时产生的塑变裂纹;且具有高强度、高抗渗透性、高耐久性,是一种应用于公路建筑工程的好材料。 A large number of tests show that fly ash cement concrete has the advantages of good workability, saving time and mixing, saving cement and reducing the temperature rise of hydration heat, reducing the plastic deformation cracking caused when the concrete is not finished, and has the advantages of high strength and high penetration resistance Sexual, high durability, is a good material used in highway construction.
