vvvHigh Range Soundless Cracking Agentvvv

　　HSCA is a noncombustible and nonexplosive material, it is safe and convenient in transportation, storage and operation.
　　HSCA is a silent demolition agent which does not cause any vibration, noise, flyrock, ash and hazardous gas during demolition.
　　 Demolition and cutting are allowed to be used according to working scheme. HSCA can gain a high yield for mining of granite, marble etc. It is very easy to crush & remain reinforced concrete structures on demand during demolition.
　　Easy to operate at job site.

　　1、Depending on usable temperature, there are three types of HSCA to be supplied.

　　2、HSCA is a kind of inorganic material consisted of calcium, silicon, iron and aluminium in the form of powder.
　　3、The expansive pressure of HSCA.
　　The HSCA slurry should be poured into hold drilled into rock or concrete. The expansive pressure can be introduced in the HDES in 3-20 ours after filling, making rocks, granite and white marble crack. The cracks further spread and vecome wider and wider with time so as to root our easy to rocks,etc.
　　4、HSCA products are packed in moistureproof boxes and each box contains four plastic bags, each of which holds 5kg HSCA powder. That is, 20kg HSCA powder per box. To keep dry in storage, about a year of time of efficacy can be reached.

　　Mining and cutting of marble and granite. The tield is 2-3 times higher with HSCA than by current explosion method. Because of non vibration crush, the yield is also doubled. Crushing and demolition of structures of concrete and reinforced concrete HSCA can be applied in the field where cracking by means of exposice is not suitable. While crushing and demolition is carrying, workshop and traffic near operating site is still.

Hole diameter and hole space：Hole diameter:30～50mm Hole space in accordance with the following formula A=KD Where, a hole space(MM) D-diameter(MM) K-cracking coefficient

　Drilling：Drill hoill hole with an air drill according to the requirements of design.
　Stirring devices ：10-20L plastic or metal barreel mixer: allow a small amount of HSCA to mix by hand. But need using rubber blove. Measuring water devices: measuring glass protector, rubber glove, protective glasses.
　Stirring：Pour about 1.5L clean watrer into a container and add one bag of HSCA slowly (Pour water 30% of HSCA by weight), then mix well with a mixer until it becomes a slurry of good fludity.
　Filling：first of all, clean up the holes before filling, HSCA slurry should be poured into hole whthin 10 minutes after mixing with water. For horizontal holes, a grouting pump and a plug for stopping up are required, or fill the holes with thick paste of HSCA.
　Cracking and cutting time：the cracks appear in 3-20 hours after filling, depending on air temerature of rocks and concrete. The cracks further spread and become wider and wider with time.

　For safety, always use industrial gloves and protective eye wears when working. After filling do not look at any hole closely and directly.
　If skin is stained with some HSCA slurry, immediately wash away is necessary, in order to prevent hurt from corroding by the slurry.
　Make a choice among the types of HSCA products and use one which is suitable to working temperature. Keep dry in storage.
