Outline of our mortar spray system and material

In 1994, our R&D has been started according to strong requirements of contractors, who had been applying the conventional shotcreting method. Since then, we have continued development of the system through trial and errors and now our good reputation is widened to overseas market rapidly.

The requirements were
(1)	Much quick setting spray method	for cost effectiveness and safety
(2)	Much less rebound	for less work for cleaning
(3)	Much less dusts	for worker's health
(4)	Simple and easier operation	for less chance of accident
(5)	Human and Environment friendly material	for workers and globe

After 2 years of trial and errors, we have brought an innovative technology product in both material and the spray system in the domestic market.
i.e. we DENKA and MCM alliance team has met all of the above requirements of customers. Actually we have dominated domestic market by our technology now.

Features are
Very Quick setting and hardening	15 N/mm2/24Hours/20℃
Near-zero rebound	1~2%
Applicable for wet/watery roof/wall surface	7 Liters/minutes acceptable
Easy nozzle handling	about 3kg of nozzle at low pressure
Flexible in STOP- RUN (less waste)	Waste mortar remained in hose only.
Easy and simple operation	By automatic control system
Well size-controlled sands	Max size of sand particle = 3mm
Synthetic fiber contained	For better flexural strength

Consequently;

Much simple operation to avoid human error
Cost minimized by shorter construction time
Safety much increased by quick setting and hardening
Friendly to Health and Environment
