EXPANSIVE POWDERS WITH NANOMETRIC ADDITIVES.

摘要

The present disclosure is related to the formulation of an expansive powder based on calcium oxide and Portland cement which has advantages over the previous patented formulations by having nanometric additives that improve the performance of the material by presenting greater expansion pressures under similar conditions than a formulation without the aforementioned additives. The use of this material thus has the advantage over those materials previously known in that the concrete or rock fracture is performed in shorter times, thereby reducing costs in demolition works or exploitation of mineral deposits.
