    摘要： 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.

    摘要： A method for producing a composite of a water hardening substance and a fibrillated organic film network having its primary strength in one direction. A plurality of layers of expanded fibrillated organic film network are incorporated in a water hardening substance such that the primary strength directions of the layers are a ligned to form at least one mass of green material. The or each mass is then formed into a structure in which the primary strength direction of the layers of expanded organic network extend in at least two directions. This structure may be a laminar structure formed by superimposing sheets of green material, or a helically folded structure.
