In the present article, the research results of concretes modified with a polymer dispersion of vinyl-benzene and acrylic (PC1) and with a styrene-butadiene dispersion (PC2) are discussed. Concretes were exposed to diesel, non-ethylated fuel, and the standard mixture of light liquids for 1000 h. Concretes modified with polymer dispersions, especially with the styrene-butadiene dispersion (PC2), indicated a smaller degree of liquid penetration into the depth of samples compared to the control concrete. The compressive strength for tested concretes, determined after 1000 h of storage in crude-oil products, in comparison to the strength of samples stored in de-mineralized water was significantly decreased, with the maximum differences equal to 12% for PC2 concrete.
在本文中,讨论了用乙烯基苯和丙烯酸聚合物分散体(PC1)以及丁苯橡胶分散体(PC2)改性的混凝土的研究结果。混凝土分别暴露于柴油、无铅燃料和轻质液体标准混合物中1000小时。与对照混凝土相比,用聚合物分散体改性的混凝土,特别是用丁苯橡胶分散体(PC2)改性的混凝土,液体渗入样品深度的程度较小。在原油产品中储存1000小时后测定的测试混凝土的抗压强度,与储存在软化水中的样品强度相比显著降低,PC2混凝土的最大差异等于12%。
