Abstract: A process for the preparation of a concrete structure including casting a layer of concrete, application of a waterbased curable resin system on the wet cast concrete layer and subsequently mechanical incorporation of the waterbased curable resin system into the concrete layer. The mechanical incorporation of the waterbased curable resin system into the concrete layer, which can advantageously be combined with trowelling of the cast concrete surface, the adhesion of a subsequent applied coating onto the thus treated concrete layer is significantly improved particularly in relation to peel strength. Further, a coated structure prepared by this process, which is particularly a floor.

Abstract: A method for treating desulfurization slag involves conveying desulfurization slag from pig iron desulfurization to a unit where the desulfurization slag is melted at a temperature of at least 1,400° C. In the unit, a thorough mixing is achieved. The treatment takes place in the unit under oxidizing conditions. Sulfur dioxide is generated and collected from the roasting gas and supplied for further utilization.

Abstract: The invention relates to a method for treating desulfurization slag, in which desulfurization slag from pig iron desulfurization is conveyed to a suitable unit in which the desulfurization slag is melted at a temperature of at least 1,400° C., said unit assuring a thorough mixing, and the treatment takes place in the unit under slightly oxidizing conditions, with the SO2 generated being collected from the roasting gas and supplied for further utilization.

Abstract: A locking system comprises a cabinet having unframed swinging glass doors and a hasp for securing the doors in the closed position. The hasp comprises a base plate, a staple plate hingedly secured to the base plate and an L-shaped back plate having a latch staple. A first leg of the back plate and the base plate are mounted to the floor of the cabinet in a juxtaposed position with the back plate positioned on top of the base plate so that the upstanding leg of the back plate acts as a door stop when the doors are closed with the latch staple protruding therebetween. When locking the cabinet, the staple plate is swung about its hinge so as to be positioned parallel to the second leg of the back plate with the latch staple extending through an elongated slot in the staple plate and a padlock is passed through the latch staple to lock the cabinet doors.
