Abstract
The invention also relates to a Portland-type cement which rapidly acquires mechanical strength, which has a shelf-life of up to 20 years under normal service conditions and which contains 4 % molybdenum trioxide. The inventive cement is characterised in that it has a fineness of more than 4200 cm2/g. The invention is also characterised in that the cement has a minimum strength of 900 psi at 100 DEG F for 8 hours from the moment of setting and in that the cement has a minimum strength of 2000 psi at 140 DEG F after 8 hours from setting, without the addition of any additives, which enables the water reduction necessary in order to achieve a pre-determined slump. The purpose of the present invention is to protect chemical technology useful for manufacturing Portland cement, thus not only regarding quarry mechanical problems, materials, machinery projects, or energy or fuel savings.
