Abstract

1.- Procedimiento para la preparación de un cemento de tipo esferosilicato en polvo, que endurece en frío y que desarrolla al cabo de 4 horas a 20c una resistencia a la compresión superior o igual a 15 mpa con una relación agua/ aglutinante comprendida entre 0,20 y 0,27 conteniendo el citado cemento los tres elementos reactivos siguientes: a) un oxido aluminio-silicato (2sio2 , a12o3) que tiene el cation a1 en coordinación (iv-v) como se ha determinado por el espectro de análisis de resonancia magnética nuclear massnmr para 27a1 ;b) un disilicato alcalino de sodio y/o de potasio, (na2 , k2) h3sio4);c) un silicato de calcio caracterizado porque las relaciones molares entre los tres elementos reactivos son iguales o están comprendidas entre (na2k2 (h3sio4)2 0,40 y 0,60 (2sio2, a12o3) ca++ 0,60 y 0,40 (2sio2o3) de tal forma que (na2 k2 (h3sio4)2 + ca++ = 1,0 (2sio2 , a12=3) con ca++ que designa el ion calcio perteneciente a un silicato del calcio débilmente básico cuya relación atómica ca/si es inferior a 1. 3.- cemento del tipo esferosilicato preparado según el procedimiento según una de las reivindicaciones 1 o 2, caracterizado porque el citado disilicato alcalino es el disilicato de potasio k2(h3s(o4)2 ;el cemento del tipo esferosilicato corresponde a la formación de un material de policondensacion mineral del tipo (ca,k)-poli(sialato-siloxo) de formula que varia entre (0,6k + 0,2ca) (-si-o-al-o-si-o-), h2o y (0,4k + 0,3ca) (-si-o-al-o-si-o-), h2o.1.- Procedure for the preparation of a powder sphero-silicate cement, which hardens in the cold and which develops, after 4 hours at 20c, a compressive strength greater than or equal to 15 mpa with a water / binder ratio between 0 , 20 and 0.27, said cement containing the following three reactive elements: a) an aluminum-silicate oxide (2sio2, a12o3) that has the cation a1 in coordination (iv-v) as determined by the analysis spectrum of massnmr nuclear magnetic resonance for 27a1; b) an alkaline sodium and / or potassium disilicate, (na2, k2) h3sio4); c) a calcium silicate characterized in that the molar ratios between the three reactive elements are the same or are between (na2k2 (h3sio4) 2 0.40 and 0.60 (2sio2, a12o3) ca ++ 0.60 and 0.40 (2sio2o3) such that (na2 k2 (h3sio4) 2 + ca ++ = 1.0 (2sio2, a12 = 3) with ca ++ that designates the calcium ion belonging to a weakly basic calcium silicate whose relation atomic ca / si is less than 1. 3.- cement of the sphero-silicate type prepared according to the process according to one of claims 1 or 2, characterized in that said alkaline disilicate is potassium disilicate k2 (h3s (o4) 2; cement of the sphero-silicate type corresponds to the formation of a mineral polycondensation material of the type (ca, k) -poly (sialate-siloxo) of formula that varies between (0.6k + 0.2ca) (-si-o-al-o -si-o-), h2o and (0.4k + 0.3ca) (-si-o-al-o-si-o-), h2o.
