Product Description

Product Introduction

SCASTAR Soundless Cracking Agent is a new type of static cracking powder material, which is the best solution to stone mining and cutting, demolition of concrete constructions as well as some other cracking and demolition solutions with special requirements such as safety and environmental pollution. It will expand in the pre-drilled holes on concrete or rock during a controllable time after mixed well with clean water. The whole cracking process is completely without explosion, noise, ground vibration, toxic gas, dust or any other environmental pollution when operate properly. SCASTAR soundless Cracking Agent stands out above the similar products for its excellent properties, low consumption, convenient operation, high expansion efficiency.

Technical Advantages

1. Easy to use: Take a certain amount of this product according to the service conditions, put into quantitative water and make mixture.

Excellent flow property: High-performance surface active component makes the flow property and grouting more better

2. Speed broken: This product has good expansion effect and large expansion pressure, and the expansion effect appears in 5-24 hours.

3. High security coefficient: The product formulation can be designed according to customers’ requirements, so sufficient operating time is left to avoid the operating risks.

4. Stable product performance: Guarantee the product’s stability by selecting raw material with stable properties and doing precise product quality test.

Setting Time: Initial Setting>= 10min, final setting<150min.

Application Scope

1. Crushing and demolition of reinforced concrete structures.

2. Safe crushing and demolition of rocks, furnace lining, open caisson engineering, underground engineering, seabed engineering and some other special projects.

3. Mining and cutting of granite, marble, jade and other stones.

Usage and Steps

1. Preparations: Select right types that is adapted to local environmental temperature, also tools as following: clean water, bucket, mixing container, protective goggles, rubber gloves, drill and so on.

2. Drilling: Design for the aperture, pitch-row, bore depth and array pitch is mainly related to the material property, structures, shapes and crushing requirements. It needs bigger aperature, shorter pitch-row and shorter array pitch if the stones or concretes have harder material property, stronger strength and fewer free surfaces. Refer to following table about the situations of different broken objects from construction experiences.

3. Mixing : Mix ratio 1 : (0.26-0.30) (which means :5 kilograms of SCASTAR need 1.3-1.5 kilograms water). Blend it well at once by mixing tools or hands (Wear rubber gloves). The stirring time should be 1-2 minutes.

4. Filling : Make sure holes are clean, no water, slag and other sundry goods left inside. All holes such as slant holes and horizontal holes need plugging to avoid slurry flowing out except vertical opening holes. For high temperature, the whole mixing and filling process should be quick and continuous and the filling should be finished in 10 minutes, or else the slurry won't be poured into due to fluidity loss. For mass objects' crack, the operators should coordinate and adopt "team work". During each loop operation,one group cannot deal with too many holes. To ensure perfect crack, pay attention to synchronization so that expansion pressure in all holes appears almost at the same time.

5. Maintenance : In Summer and Autumn, the construction needs no maintenance and it usually takes only 5-24 hours to crack. In Spring and Winter, it should take necessary maitaining measures, and the cracking time is usually in 20-30 hours. The lower the temperature is, the longer cracking time it takes.

Package and Storage

The product is packed by special plastic bag inside while remarked paper carton outside, with each bag 5 Kg and each carton containing 4 bags. Customers' good and reasonable Package requirements are also available.

The product should be sealed and stored in a dry place. Have been opened or unused product should be well sealed timely to prevent moisture and losing effectiveness. If product has broken package or moisture, it should not be used.

Safety Instructions and Announcements

1. Non-construction workers are not allowed entering the construction site during the whole breaking process. Signs must be displayed at construction site to warn irrelevant staff and prevent injury.

2. Wear protective goggles and rubber gloves during the mixing and filling process. Mustn’t look into directly after each hole being filled in case of orifice injuries. Leave the construction site as soon as finished the filling.

3. For strong alkality, if it touches skin or goes into the eyes, wipe by vegetable oil, wash by clean water and go to the hospital immediately.

4. Carefully select the proper types according to the environmental temperature, and prevent products of different types being mixed.

Statement: Please read the operating construction carefully, and act in accordance with the requirements of product transportation, operation, usage and storage. All responsibilities to consequences of personnel injuries or accidents due to violation of instructions should be taken by the party that has violated the operating instructions.
