To maintain quality, additional materials (blends), fiber, or other substances are added during the process, creating chemical-free building materials mixed and processed according to specific values and ratios, [1,2].
Hardened concrete, also known as artificial rock, consists of materials filled with fine aggregate or sand interspersed between coarse aggregate or crushed stone, cement, and water (cement paste).
Materials The materials used in the production of normal-quality concrete include Portland Cement Composite (PCC), coarse aggregate (natural stone), fine aggregate (sand), shell ash, hemp fiber, and water.

To see the properties of these materials that will be enough to use as a pozzolanic material to some degree.
So these materials will be used to maximum benefit in improving the property.

In this regard, different formulas of multiple emulsions based on paraffin oil have been developed in order to investigate the effect of hydrophilic surfactants and GX used at different concentrations on the stability and rheology of multiple emulsions prepared. 2 Materials and Methods 2.1 Materials The oil phase used in this study consisted of paraffin oil (U.E SARL PROCHIMA SIGMA, Germany).
After pre-shearing the sample was kept at rest for 600 s prior to measurements in order to permit the material recovering its initial structure partially at least.

The traditional fibres used within the cement-based materials are mostly made from steel, synthetic or glass (Bentur and Mindess, 2007).
Materials and specimens Ordinary Portland cement CEM I 42,5 N and quartz sand fraction of 0-4 mm were used for the production of mortars.

Vortex reactor The characteristics of vortex reactor The core of micro-eddy current coagulation is vortex reactor, Vortex reactor is the porous hollow sphere that made of ABS plastic-based material, Inside and outside the sphere surface made into rough surface, surface has small holes, aperture and the opening rate in accordance with the determination of water treatment.
It has the following characteristics[1] : (1) the flow velocity and orientation changes in through-hole water flow, in addition, the friction of both inside and outside the wall resistance, Have a micro-flow vortex flow;(2) Easy construction, Without the installation of fixed, No direction requested, it can be put into the pool directly;(3) Materials have good strength, not toxic, Corrosion-resistant, Anti-aging, Service life of several decades;(4) Simple structure, Management convenience, easy operation and maintenance, Up to the water in the stream will float and rotate, can not easily be blocked floating
* project (50868005) supported by National Natural Science Foundation of China Figure1 the vortex reactor coagulation schematic diagram Principle of eddy current reactor[2,3] Attaining the better coagulation-flocculation effect, the micro-whirling reactor can create the better hydraulic condition with respond to each kind of intrinsic hydraulic factors.
