Described above is only the general introduction of technical solution of the present invention, in order to better understand technological means of the invention,
And can be practiced according to the content of specification, described in detail as after with presently preferred embodiments of the present invention below.
Specific embodiment
Further to illustrate the present invention to reach technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Preferred embodiment, to according to portland cement proposed by the present invention, its specific embodiment, structure, feature and its effect, in detail
Illustrate as after.In the following description, what different " embodiment " or " embodiment " referred to is not necessarily same embodiment.Additionally,
Special characteristic, structure or feature in one or more embodiments can be combined by any suitable form.
The present invention provides a kind of silicate cement raw material.
The component of silicate cement raw material for providing of the invention and the mass fraction of each component are：
The primary raw material of the raw material of portland cement of the present invention is the stone of calcium carbonate content relatively low (being less than or equal to 50%)
Limestone chips.And (such as the place of production is the SiO in Hebei Handan by the clay from high-quality2Content clay higher), add it is appropriate
