Safety Precautions
Even though it is safe demolition technique, as the product is chemically highly base in nature with pH-13 ++ it is necessary to take proper care while handling and applying. Being safe is prime important to do a safe demolition. Always wear hand gloves while handling and wash hands thoroughly after use. Ingestion this product causes severe damage to digestion system of human body. If it comes in contact with eyes do not rub your eyes and rinse with clear water several times and contact an eye doctor at the earliest to avoid major damage to eye.

Stone Crack Powder
5 Metric Ton (MOQ)
We are offering stone cracking powder that is used in demolition of rock and concrete structures in dust and noise sensitive areas and places closed to inhabited areas, natural gas lines, pipelines, roadways or other areas where the use of explosive would generate significant safety risk. It is a non-explosive demolition agent used to demolish rock and concrete structures through eco-friendly procedure. It is a non-toxic and powdery material, which consists of oxides of calcium, silicon iron and aluminium. When it mixes with clear water (ph=6.5~7) and poured in drilled hole, it subjects to hydration reaction liberating heat energy and it swells while hardening creating a significant expansive pressureforce on the hole wall face at 600 psi of pressure. It is strong enough to split and fracture marble, granite, limestone, sand stone, concrete, reinforced concrete, virgin boulders ledge and piers etc without any sound and flying rock. Productive sca can be used where explosives are forbidden and extensively in granite industry to avoid unwanted cracks in the material. Use of explosives to split the big blocks highly prone to internal crack development which may leads to reject the material for exporting. So, replacing the explosives with ‘productive sca’ will result in significant increase in productivity. advantages It does not make any noise, explode or generate fly rocks, vibration or toxic fumes. It is completely harmless and environment friendly. At the other side, explosives are less safe and pose the threat of premature explosion, misfire and fly rocks, posing a significant threat after the planned explosion and also chances for uneven cracking and internal crack development. So, usage of “productive sca” is very productive and safe. Usage of productive sca has become a common procedure in demolition in inner citied, other dust and noise sensitive areas. “productive sca” has also used when excavating rock, or demolishing concrete structures or components of concretes structures are closed to inhabited areas, natural gas lines, pipelines, roadways or other areas where the use of explosive would generate significant safety risk.

Principle of Working
Expansive Mortar is being manufactured from burnt lime having high purity Calcium Oxide which has property of volumetric expansion on hydration reaction with water. The principles applied in using âExpansive Mortarâ are very much similar to those ones followed in traditional blasting techniques. As like for explosives, holes must be drilled to contain âExpansive Mortarâ which must thoroughly be mixed with a measured quantity of water and poured into the holes. Few minutes after filling, a reaction of hydration will takes place generating heat, crystallizing and expanding while hardening. If hydration takes place under confinement, significant expansive pressure will develop resulting cracks along the line of holes. A person who can deeply understand hydration reaction and Expansion process become an expert in this product application. No need for detonator, ignition and certified explosive operators.

Packing & Storage
Expansive Mortar is available in powdered form and will be packed in 5kgs Moist-proof bags. One strong export type carton will be packed with 4 Nos of 5kg bags. 50-60 cartons per pallet/crate.Moisture is major threat for this product. While storing, do not place the boxes directly on the floor, instead, provide wood Insulation from the ground and wall faces to avoid ingress of moisture. Material stored in this manner, can be effectively used for about 1 year.The bag should be unpacked before use only. Do not use previously opened packs as it already absorbed moisture from atmosphere and lost properties.While storing a portion of powder remained after use, evacuate the air from the bag, and then seal it with suitable means so that air does not ingress into the bag and use as soon as possible. However, as it already exposed to moisture there is a risk of losing its effectiveness once the bag has been opened.If you receive broken bags they may not work due to chance of moisture absorption. Please report to suppliers immediately about the same.

Cracking Mechanism
After the mortar has poured into holes drilled on rock or concrete, the expansive stress gradually increases with time, the material to be cracked undergoes a process of: Crack initiationCrack propagationThe increase of crack width The mechanism by the expansive stress of âProductive SCAâ is shown in Fig. 1. Cracks initiate from an inner surface of the hole due to circumferential stress that develops during expansion process while hardening. The expansive stress continues even after the appearance of cracks, the cracks propagate and also new cracks initiate during the process. Usually, For a single hole, 2-4 cracks initiate and propagate either towards nearest free surface or nearest hole. When a free surface exists, the crack, as shown in Fig. 2, is pushed apart mainly by the shear stress, and a secondary crack also arises from the bottom of the hole, running toward the free surface. Please note during the initial reaction process (i.e., 30-60mis) there are chances for blow-shot releasing gases evolved in the hydration reaction. So, during that period we insists workers to stay away at least 10 mts from Job place. Peeping onto the hole strictly prohibited.
