Before half-the century end 20th, many research works of inorganic absorbent resistant substance making were carried out in many countries all over the world (Internationnales Symposium: “75 Jahre Quellzement”11-13 Dezember 1995–Weimar; Bundesrepublik Deutschland). Mostly, these works also focus on study to make absorbent resistant additive types under the inorganic compound form. As mixing with Portland cement, it will turn into absorbent resistant stretched cement making the more stable construction project, and it may be able to resist endosmosis well in order to ensure the permanent absorbent resistance according to longevity of the construction projects corresponding to tropical climate region.

On the above said base, our study project only concentrate on study to make absorbent resistant additive types under the inorganic compound form, process absolute absorbent resistance in order to assure the permanent absorbent resistance on the longevity of the construction projects.

Our products are produced with high quality on the top quality standards of the world and Vietnam
