摘要： The present invention regards a superfluidifying additive for cementitious compositions, comprising an acrylic superfluidifier, an ammonium salt, at least one surfactant, and possibly an antifoaming additive. The present invention moreover comprises high-fluidity and high-workability cementitious compositions premixed in the dry state and cementitious items containing the said superfluidifying agent.

摘要： A superfluidifying composition for cement compositions is described, which contains as superfluidifying additive a salt of the product resulting from sulfonation and oxidation of fuel iols deriving from steam cracking of oil products (FOKS), and an antifoam additive comprising one or more copolymers among ethylene oxide and propylene oxide, etherified at the beginning of the polymeric chain by an alkoxy group, R1-O, wherein R1 is an alkyl group, linear or branched, having from 2 to 20 carbon atoms, and whose monomeric terminal units have their oxygen atom bound to a hydrogen atom.

摘要： The present invention concerns a composite cement paving with photocatalytic action for reducing urban polluting agents, composed of a bituminous or cement foundation, a resin having the function of interface, a superficial cement layer with photocatalytic properties able to reduce organic and inorganic polluting agents, said paving also comprising reinforcing materials and possible suitably positioned fibrous materials. The paving thus realised presents a strong photocatalytic action, prolonged overtime, even in the presence of high mechanical stress caused by heavy traffic.
