摘要： Copolymers based on unsaturated monocarboxylic or dicarboxylic acid derivatives, oxyalkylene glycol alkenyl ethers, vinylic polyalkylene glycol, polysiloxane or ester compounds and the use thereof as additives for aqueous suspensions based on mineral or bituminous binders are described. The copolymers give aqueous suspensions of building materials excellent processing properties even in very small amounts, without delaying strength developments. In addition, when the copolymers of the invention are used, a drastic decrease in the water/binder ratio still leads to highly fluid building materials without segregation of individual constituents from the building material mixture occurring.

摘要： A description is given of pulverulent polymer compositions based on polyether carboxylates, which are characterized in that they comprise a) from 5 to 95% by weight of a water-soluble polymer made up of polyoxyalkylene-containing structural units, carboxylic acid and/or carboxylic anhydride monomers and, if desired, further monomers, and b) from 5 to 95% by weight of a finely divided mineral support material having a specific surface area of from 0.5 to 500 m2/g (determined by the BET method in accordance with DIN 66 131). These pulverulent polymer compositions, which can contain up to 90% by weight of polyether carboxylate, have a significantly increased sticking and caking resistance compared to spray-dried products and have further advantages when they are used in cement-containing building material mixtures.

摘要： Copolymers based on unsaturated dicarboxylic acid derivatives, oxyalkylene glycol alkenyl ethers, unsaturated dicarboximides and/or -amides and vinyl monomers are described, as also their use as additives for hydraulic binders, especially cement. The copolymers also have an excellent plasticizing effect—even if they are added in large quantities—when used in concrete mixtures with an extremely low water content, and they do not retard the setting process.

摘要： Disclosed is a co-polymer based on oxyalkyleneglycol alkenyl ethers and unsaturated dicarboxylic acid derivatives, as well as vinylic polyalkyleneglycol, polysiloxane or ester compounds. These co-polymers can be used as additives for hydraulic binding agents, especially cement. The co-polymers of the invention have an excellent and long-lasting liquefying action without introducing large amounts of air pores into the binding agent mixtures, thereby preventing the loss of strength and stability of the hardened building materials.

摘要： Supporting apparatus for supporting bridge portions on a portable bridge of the type including a plurality of bridge portions movable from storage positions to positions of use connected to one another in series. The supporting apparatus includes two support legs spaced from one another and swingably supported at respective free ends of a pair of pivotally connected carrier sections. The support legs are further connected with one another by a hydraulic-cylinder arrangement arranged in bypassing relationship to the carrier sections with the holding element designed to absorb relative movement of the support legs resulting from the pivotal connection of the carrier section. Swinging devices are also provided at the free ends of each of the carrier sections for applying forcible swinging movement to the support legs so as to fold same from storage to in-use positions. The pivot axis of the support legs extend at an angle of less than 90.degree. with respect to the longitudinal extent of the support legs.
