Abstract
Provee mezclas cementicias, particularmente para ser usadas como materiales aglutinantes para torcreto (concreto aplicado por rociado). También provee unmétodo para producir dichas mezclas sistemáticamente. El torcreto resultante tiene características de fraguado rápido, tan bajo como 5 a 10 minutos, altaresistencia temprana a la compresión (5 a 25 MPa en fraguado de dos horas, 20 a 60 MPa en fraguado de un día), alta resistencia compresiva permanente ycontracción megligible. En las mezclasse usan escorias de cemento de alto contenido de alúmina con yeso anhidro, cal, piedra caliza, bentonita y otrosaditivos. Estas mezclas son especialmente adecuadas para su uso en ingeniería de torcreto. Los métodos para usar el torcreto mejorado son similares a losmétodos de uso del cemento Portland con un rebote significativamente reducido en situ.Provides cementitious mixes, particularly to be used as binder materials for torcrete (spray applied concrete). It also provides a method of systematically producing such blends. The resulting torcrete has fast setting characteristics, as low as 5 to 10 minutes, high early compressive strength (5 to 25 MPa in two hour setting, 20 to 60 MPa in one day setting), high permanent compressive strength, and megligible shrinkage. . High-alumina cement slag with anhydrous gypsum, lime, limestone, bentonite and other additives are used in the mixes. These mixtures are especially suitable for use in torcrete engineering. The methods for using the improved torcrete are similar to the Portland cement use methods with significantly reduced rebound in situ.
