METHOD FOR MAKING CONCRETE WEATHER-RESISTANT |
摘要 |
<p>The invention relates to a method of making concrete used in hydrotechnical structures weather-resistant as regards the freezing of water absorbed into the pores of the concrete. The problem in this connection consists of the expansion of freezing water and the consequent state of tension in the concrete. According to the invention, a small amount of micro-sized rubber powder is mixed with the concrete mix, the rubber particles forming even-surfaced, closed buffers into which the water expanding when it freezes can expand without producing states of tension in the concrete. The rubber particles are ground from the rubber parts of used automobile tires.</p> |
