Crackamite is a soundless, non- explosive and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any explosion, noise, ground vibration, gas, dust or any other environmental pollution when used properly. Crackamite is a non-toxic powder consisting of oxides of calcium, silicon and aluminum. The chemical composition of Crackamite is a powder consisting of an inorganic compound made mainly of a special kind of silicate and an organic compound. Crackamite does not contain any harmful components. Crackamite provides the most technically suitable and cost-effective solution in restricted demolition of rock and concrete structures where nearby structures must be protected from shock waves generated by explosives. Explosives are expensive due to long operating times, special transport, storage and handling precautions, and the need to comply with public safety regulations. As requirements for demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned. Crackamite is the solution. Marble, granite, limestone, plain concrete, reinforced concrete, boulders, and ledge are fractured overnight without noise, vibration, or fly rock. Where Can Crackamite® Be Used? Marble Quarrying Granite Cutting Rock Breaking Limestone Mining Stone Cutting Concrete Demolition Crackamite is versatile in its usage Crackamite can be used on any type of stone formation, concrete, reinforced concrete or tiled structure in: Quarrying of marble, granite, limestone, sandstone, etc. Stone cutting 1 Removing boulders Breaking rock into pieces Excavating foundations Leveling stones for road works Excavating trenches for pipe-laying Underground excavations Demolition of concrete or reinforced concrete objects Demolition of foundations Demolition of breakwaters or jetties Demolition of tiled and refractory structures, and more In the field as a new method of demolition, Crackamite can effectively be use in the construction and civil engineering fields as follows: Bridges Ledge Machinery Bases Slabs 6 " thick and more Dams Boulders Concrete Piers Marble and Granite Crackamite can be used on any type of rock formation, concrete, reinforced concrete or tiled structure in: excavating foundations; leveling rocks for road works; excavating trenches for pipe-laying; underground excavations; 1 marine and submarine excavations; removing boulders; demolition of concrete or reinforced concrete poles, towers, walls, etc.; demolition of foundations; demolition of breakwaters/jetties; demolition of tiled and refractory structures.

  • Installation Details for Kerb & Edgings
    INSTALLATION DETAILS FOR KERB & EDGINGS Health and Safety Information Safe working practices should be employed at all times during the construction process and all necessary Personal Protective Equipment (PPE) should be worn. Drainage All paved surfaces require drainage. Where kerbs or edging are laid, this will restrict natural water flow off the paved area, so provision needs to be made to dispose of this water. This can be in the form of using cross fall and longitudinal fall to run water into areas of soft landscaping (i.e. a flowerbed or grassed area). However, where this is not possible, some form of drainage channel will need to be utilised. If laying kerbs or edgings next to a building, then care should be taken that the laid products are at least 150mm below the damp proof course level. Excavation To allow new kerb or edging to be installed correctly a certain amount of excavation will normally be required. The depth of this excavation will depend on several factors; the height of the kerb or edging selected, which way up it will be laid, and what upstand is intended. (i.e. the difference in height between the top of the kerb or edging and the paved surface in front of it). All organic materials such as grass should be removed from the excavation as this will rot and could cause possible settlement of the kerbs or edging and paving at a later stage. When the desired level has been reached the bottom of the excavation should be compacted to give an even surface.

  • Cemetery Preservation QUICK TIPS
    Georgia’s State Historic Preservation Office IIIIIICCCeeemmmeeettteeerrryyy PPPrrreeessseeerrrvvvaaatttiiiooonnn QQQUUUIIICCCKKK TTTIIIPPPSSSIIIIII Common Monument and Gravemarker Materials Below are brief descriptions of the most common stones and monument material types found in Georgia. Stones vary in hardness and therefore in their ability to survive satisfactorily outdoors in cemeteries, as well as their ability to withstand cleaning or restoration. The Mohs Scale of Mineral Hardness, created in 1812, establishes talc as the softest mineral material and diamond as the hardest. There is no need to determine the exact hardness of a stone you are working on. However, seeing how some common cemetery materials rank on the Mohs Scale can guide your choice of the best methods for working with them: Talc (see "soapstone" below) Marble Sandstone Granite Diamond 1 3-4 5 7-8 10 If identifying the type of stone is difficult, but will be important to a cemetery preservation project, referring to a stone/mineral field guide is recommended, or consulting with a geologist or other expert. Marker Material Descriptions MARBLE Marble has been used for a great many markers in historic cemeteries in Georgia. The state's marble industry dates back to the late 1830s, when outcroppings of surface marble were discovered in north Georgia. Quarrying began, and markers were carved and sold throughout the area. The Georgia marble industry still thrives today. Several different types of stone that can be polished are called marble. A true marble, though, is a metamorphic rock made up of calcium carbonate, traces of silica and iron oxides; it is rather soft and easily carved.

  • A Masonry Wall and Slide Repair Using Soil Nails and Rock Dowels Drew Gelfenbein, Christopher Benda, PE and Peter Ingraham, PE 1.0 Background
    A Masonry Wall and Slide Repair Using Soil Nails and Rock Dowels Drew Gelfenbein, Christopher Benda, PE and Peter Ingraham, PE 1.0 Background In the middle of August 2003, Vermont experienced several days of very heavy rains which precipitated a slide failure on Vermont Route 73 in Forest Dale at approximately mile marker 6.36. A blocked culvert on the south side of VT 73 caused an overflow of water across the road surface and over an asphalt and wood curb down an embankment. This resulted in a significant amount of erosion, undermining of the road surface (Figure 1) and a washout of a timber cribbing retaining structure Figure 1: Undermining of north side of VT 73 located on the top of a mortared masonry wall (Figure 2). in Forest Dale. In the project area, VT 73 is constructed on a retained embankment in steep terrain formed in sub-vertically dipping schistose meta-greywacke. The embankment along a valley sidewall was originally built by constructing masonry retaining structures to span between a series of rock knobs. Soils mantling the rock in the valley consist of dense glacial till. The natural terrain was incised by the Neshobe River, which occupies the valley floor approximately 80 feet below and 100 feet north of the project retaining walls. After site visits by Vermont Agency of Transportation (VTrans) staff, it was decided that the laid up masonry wall immediately west of the slide area was also in desperate need of repair. The laid up masonry wall (Figure 3) was observed to have broken and missing blocks.

  • TIPS for MIXING MORTAR for MASONRY Masonry Cement Is Basically Normal Portland Cement with Ingredients to Provide the Plasticity Required for Masonry Work
    TIPS FOR MIXING MORTAR FOR MASONRY Masonry Cement is basically normal Portland cement with ingredients to provide the plasticity required for masonry work. Masonry cements are pre-packaged as either Type N Masonry Cement or Type S Masonry Cement. Type N Masonry mortar is recommended for general use in non-load bearing walls as well as in exterior veneer walls not requiring high strength. Type S Masonry mortar is recommended for use in all masonry be- low grade as well as in exterior load bearing walls requiring high strength. Type N Masonry Cement or Type S Masonry Cement can also be used in parging and stucco work. DO NOT use masonry cements for concrete jobs. Masonry cements are mixed with sand in the following proportions (by volume).: 1 part Type N or Type S Masonry Cement 3 parts damp, loose brick sand Mix the cement and sand. Add water until the mortar is of suit- able “buttery” consistency. One bag of masonry cement is required to lay 35-40 blocks or 135 bricks. Caution: Freshly mixed cement, mortar, concrete, or grout may cause skin injury. Avoid contact with skin whenever possible and wash ex- posed skin areas promptly with water. If any cement or cement mix- tures get into the eyes, rinse immediately and repeatedly with water and get prompt medical attention. Keep children away from cement powder and all freshly mixed cement products. This publication is intended for general information purposes only.
