Product Description
Introduction
Shandong Shengchuan New Material Science and Technology Inc.
Shandong Shengchuan New Material Science and Technology Inc. (hereinafter referred to as Shengchuan New Material) was founded in July 2015 , Located in Zichuan, covering a floor area of 33,000 square meters and a building area of 10,000 square meters, the company has over 60 staff members including 10 technicians and 5 expert technic advisers.
Shengchuan New Material is a scientific and technic innovation-based enterprise majoring in producing advanced inorganic nonmetal material. Currently, the main products of phase 1 project include pure aluminate cement series (brand VICAL) and high-purity calcium hexa-aluminate compound material (brand RECAG) with an annual design capacity of 30,000 tons respectively. After reaching design capacity, the annual output value can reach 240,000,000 yuan. Meanwhile, the products have good industrial policy guidance (energy efficiency, environmental protection and consumption reduction) and positive social significance (sewage anticorrosion).

 Pure Calcium Aluminate Cement (refractory Binder) -Vical71Pure Calcium Aluminate Cement (refractory Binder)-VICAL71 designed to be used at high temperature and harsh environment, is a pure calcium aluminate binder with an alumina content of approximately 70%. It has outstanding performance during hydration and after exposure to high temperatures.
 
Thanks to the new design of mineral phase and special manufacture process, VICAL71 provides characteristics ideally suited for refractory applications where rapid hardening combined with excellent mechanical strength and high temperature performance are required.
 
VICAL71, a binder manufactured by the sintering process, contains only calcium aluminates. Its stable quality, ensured by serious online monitoring and control of its mineral phase, provides and guarantees successful site-installation performance and flexible formula design.
 
As a hydraulic binder without any additives, VICAL71 shows outstanding compatibility and tolerance to dosage and types of additives and micropowders in the formulations, which provides flexibility during formula optimization. Therefore, it is recommended to be used in high technology refractories, such as low cement, ultra low cement and pure corundum system.
 
The rheological properties of VICAL71 are well adapted to various installation conditions, particularly for the conditions like casting, self-flowing, gunning and shotcreting.
The chemistry of VICAL71 is particularly suitable for conditions where high purity is essential, especially for strong reduction atmosphere including carbon monoxide or hydrogen.
Specifications 
The specification has an Acceptable Quality Level (AQL) of 2.5%, with the values evaluated according to the sampling standard  ISO 3951.

Remark:  Fineness determined according to standard EN 196-6, methods for the measurement of the fineness of cement. 
Workability
The workability of VICAL71 has been determined by measuring the flow properties using the ASTM C230 flow table. The test is carried out using a standard siliceous sand mortar.
