Introduction Mineralogical materials, which are used in cement, mortar and concrete to increase their binder and some physical properties of them, differ from inert materials such as filler etc.
Mineralogical materials were also used in cement manufacturing in India as raw material.
However, mineralogical materials were mixed concrete as aggregate in South Africa in the past.
In other countries added mineralogical materials both cement and concrete.
To add mineralogical materials to cement, mortar or concrete up to 40% causes over 40% reduces on compressive strength of cement in initial days, for example 7-day, because of mineralogical materials content.

Study on the (Fe,Cr) 7C3 particles reinforced iron-based composite coating Libin Niu1,a, *, Zhen Xu1,b, Jianhong Peng2,c 1 School. of Material Science and Engineering, Xi’an University of Science and Technology, China 2College of Physics and Electronic Information Engineering,Qinghai Nationalities University,China *,a dy059@126.com, b xuzhen0913@163.com, c dy059@163.com Keywords: Reinforcement, In situ, Composite coating, (Fe,Cr) 7C3 Abstract An iron based composite coating reinforced by (Fe,Cr) 7C3 particles, with a thickness of 4.0 mm, was fabricated on the ductile cast iron substrate by means of a centrifugal casting and in situ techniques.
However, as a wear resistant material, its application is still limited [5-7].
Experimental processing Chromium wires (0.25 mm in diameter) and ductile cast iron were used as the raw materials.
In order to obtain the high volume fraction of the (Fe,Cr) 7C3 phase, the original materials should contain relatively high Cr and C contents; their chemical compositions are Fe–3.61C–2.50Si–0.28Mn–0.45Cu–0.04Cr–0.017P–0.014S (wt-%) for ductile cast iron and Fe–0.12C–0.79Si–17.54Cr–0.011P–0.013S (wt-%) for Cr wire, respectively.
