REGENERATING AND PROTECTIVE SYSTEM FOR CONSTRUCTIONS IN CEMENT AND CEMENT

Abstract: A mortar composition for application of a regenerating and protective coating on cementitious materials by means of an airless pump contains cement, aggregate and synthetic resin emulsion in fixed quantities. It is prepared by mixing the ingredients in a cement mixer until a homogeneous, free-running mortar is obtained followed by pouring it into an agitator with low rpm and agitating until complete utilisation.

Description: D E S C R I P T I O N REGENERATING AND PROTECTIVE SYSTEM FOR CONSTRUCTIONS IN CEMENT AND CEMENT This invention covers a technical innovation in the composition, processing and application of a low thickness hydraulic mortar, with regenerating properties when used on cement, cement concrete and composite material structures. The various properties of the subject mortar make it possible to utilise it in a wide range of circumstances and in many sectors of industry and building, and hydraulic works. The typology and properties of this mortar make application possible for the first time by means of an airless pump thus ensuring rapid and economical application with respect to traditional systems. The mortar, applied as described, makes it possible to obtain a coating of low thickness and which is compact and thus has excellent waterproofing, adhesive and physical and chemical resistenace properties. The typology of the system in question is determined by: 1) the choice of particle size of the aggregate of less than 200 micron which, over and above the functional requirements set out must also permit the smooth passage of the mortar through the pump, pipes, valves and an exit nozzle of approximately 45 micro" diameter, without causing excessive wear and tear. 2) relatively exact quantities in volume or weight of cements, aggregates, additives and resins emulsified in water. 3) processing achieved by: mixing in a cement mixer in order to obtain a homogeneous, free-running mortar; transfer to and continued processing in an agitator with low rpm until complete utilisation of the batch; 4) application by means of an airless pump, preferably of the diaphragm type, with a special intake filter and modification of the valves as required, with a nozzle of approximately 45 micro".

Claims: C L A I M S 1) Mortar and similar substances, for regenerating and protecting cement, cement concrete and allied substances characterized by the exact volumetric quantities of component materials, which may vary in percentage terms plus or minus 20% based on the following data: Ratio cement aggregate in volumetric quantity 1 1 Ratio cement aggregate and emulsion in volumetric quantity: 1 7 03-05; 2) Mortar and similar substances for regenerating and protecting cement, cement concrete and allied substances characterized by selected components such as: Quartz sand with particle size inferior to 200 micron; Synthetic resin emulsion, additives and water in established doses; 3) Mortar and similar substances, characterized by the following system of processing; dry mix of cement-aggregate; mixing of cement-aggregate and emulsion in cement mixer until a homogeneous, free-running mortar is obtained; pouring of mortar into an agitator with low rpm in which it is agitated until complete utilisation of batch. 4) Mortar and similar substances, characterized, according to the above claims, by the possibility of application by means of an innovative system, that is utilising airless equipment, thus ensuring enhanced quality and more rapid application with respect to traditional systems and with lower costs.
