We supply an extensive inventory of general laboratory product of the best quality and value ranging from balances and scales, thermometers, laboratory ovens, muffle furnaces, vacuum pumps, air compresors,core drills, laboratory glassware,water baths, pans, bowls,dishes, jars, trowels, brushes, shovels, spatulas and general tools. Our range of balances are designed for the lab but have the rugged features needed for materials testing. They include all metal chemical resistant die-cast housings. Compact and durable, these balances are the best choice for basic weighing and economy.
GEOTECHNICAL SOIL CATALOGUE
Soil is one of the oldest forming structures that our planet is formed from. It is a loose rocky material that is commonly used in the construction industry. It is important to test the ground soil before construction and to know the type and classification of the soil before the commencement of any project. It can be identified by several parameters, one of which the percentage of clay, silt or sand can be found in its composition. Other parameters such as moisture content, shear strength, elasticity, specific gravity, density, degree of compaction, penetration resistance, consistency, bearing capacity, hydraulic conductivity, permeability and consolidation can affect the soil characteristics and behaviour during construction. Our testing equipment as described in this section are all carefully designed and manufactured to the highest international standard necessary to achieve accurate and repeatable results
GEOTECHNICAL CONCRETE CATALOGUE
Concrete is used more than any other man-made material in the world, it is a composite construction material composed of cement (commonly Portland cement), coarse aggregates, sand, water and chemical admixtures. The word concrete comes from the Latin word “concretus” (meaning compact or condensed) hence, concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a robust stone-like material that can be molded in any shape we desire. The quality of concrete is important if structures formed from this versatile material are to be safe and serve the purpose for which they were constructed therefore, several tests are conducted to identify the characteristics and parameters of concrete.
GEOTECHNICAL CEMENT CATALOGUE
Cement is one of the ancient raw materials used in construction.It is uncertain where it was first discovered that a combination of hydrated non-hydraulic lime and a pozzolan produces a hydraulic mixture (e.g., Portland cement) harden because of hydration chemical reactions that occur independently of the mixture’s water content; they can harden even underwater or when constantly exposed to wet weather. Cement is essentially a binder that binds other materials together, Modern cements are manufactured by a chemical process. Raw materials are crushed, ground and blended before being heated in a rotary kiln until they combine chemically. The clinker from the kiln is then ground with gypsum to form Portland cement.
GEOTECHNICAL ROCK & AGGREGATE CATALOGUE
Aggregate is a component of a composite material used to resist compressive stress and provide bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. It is vastly used in most combination of construction material such as concrete and asphalt technology to which aggregates may either be specified or designed to suit a particular engineering requirement while not suiting another. The properties of aggregates can vary and hence affect the final construction material. Therefore it is important to test the different parameters such as resistance to polishing, particle size, shape and texture, relative, bulk density, crushing value, impact value, organic impurities, compacted densities, specific gravity, soundness and abrasion resistance.
GEOTECHNICAL ASPHALT CATALOGUE
Asphalt is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleum. It is most commonly used in road construction. The material consists essentially of two ingredients, aggregate and bitumen which is the binder. A number of technologies allow this simple mix to have an almost infinite number of mixtures which may either be specified or designed to suit a particular engineering requirement. It is therefore important that equipment and test methods are used to determine the different physical and chemical properties of any given asphalt mix. Such parameters include binder content, binder percentage, aggregate grading, void content, resilient modulus, indirect tensile fatigue cracking, creep, softening point, flash and fire point, water content, loss in mass, elongation, elasticity, viscosity and adhesion.
