SUNKEM PLAST SUPER

WATER REDUCING SUPER - PLASTISIZER CUM INTEGRAL WATERPROOFING CONCRETE ADMIXTURE SUNKEM PLAST SUPER is a chloride free water reducing super plasticizer cum integral waterproofing concrete admixture. These are based on selected high molecular organic polymers which when dissolved in water to provide ions with very high negative charges to allow better attraction of cement particles and adsorbed in sufficient number to form a complete monolayer around them. ADVANTAGE SUNKEM PLAST SUPER a high range super plasticizer admixture. * Import extreme workability without addition of extra water to produce flowing, bleed free, homogeneous concrete which can be poured effortless into place around congested reinforced structure with little or no vibration to achieve optimum compaction. * Allow large reduction of the water content without loss of workability. This leads to higher concrete density and strength. * Permits a simultaneous increase in both workability and strength without incurring substantial extra cost. Suitable for the construction industry to enable early stripping of form work ensuring speedy construction. * If reduces the internal friction and thixotropy of the mix to a minimum without the risk of segregation thereby making puming operation more efficient. * Beneficial effect on long term durability, permeability and a reduction in the rate of carbonation to protect the reinforcement from corrosion. USES * Casting mass concrete with heavy reinforcement where self compaction and moderate workability retention is required. * Pouring of concrete at normal or elevated temperatures. * Suitable for use any grade of concrete bellow and above ground levels. * High range water reductions minimize shrinkage or cracking, thereby producing closed textured, integrated water proofness with improved durability even in aggressive atmospheric conditions. * Suitale for use in priestesses structures, precast Industries as well as repairing structures.

SUNKEM EPOCRETE 21

LOW VISCOCITY HIGH STRENGTH INJECTABLE EPOXY GROUT DESCREPTION " SUNKEM EPOCRETE-21 " is a two component solvent free ultra low viscosity free flowing, fast curing epoxy resin system designed specially for pressure injection into concrete for carrying structural repairs. Due to its low viscosity it can be injected into extremely fine cracks also. The cured resin possesses high mechanical strength, excellent adhesion, practically no shrinkage and a chemical resistance typical of all epoxy resin system. Fine cracks and small voids can be successfully sealed with "SUNKEM EPOCRETE-21" has very high strength, the cured material is not brittle and remains slightly flexible. 'SUNKEM EPOCRETE - 21" Is supplied pre-measured quantities. Component A-Resin and Component B-Hardener. MIXING RATIO Component A : 100 parts by weight Component B : 50 parts by weight PROPERTIES Colour : Light amber Density : 1070 to 1090 kg/m3 Compressive Strength M 350 kg/cm2 in 24 hours at 30C. 800 kg/cm2 in 7 days at 30C. Tensile Strength : 150-200 kg/cm2 in 7 days at 30OC. Flexural strength : 300-400 kg/cm2 in 7 days at 30OC. Pot life : Approximately 40 minutes at 30OC Shrinkage : Practically no shrinkage. Chemical Resistance : Unaffected by a wide range of chemicals, oils etc. Storage : 24 months when unopened and kept in shade. APPLICATION DATA SURFACE PREPARATION - The area to be treated should be properly cleaned to remove dust, laitenance, grease, fungus etc. Injection nipples are fixed in a square grid maximum 500 to 800 mm c/c depending on the cracks and nature of concrete. If required for effective treatment, the grid may be reduced. Before the injection starts all cracks and crevices are to be sealed with "SUNKEM EPOCRETE - 21 " mortar and surface sealing is to be done for other porous areas. MIXING Mix all the components-B (Hardener) with Component-A (Resin) Mix for 2-3 minutes to uniform colour without any streak using drill and paddle (speed 400 - 450 R.P.M. ) mixer so as to avoid any entrapped air. Mix only sufficient material for immediate requirement. Leave the mixed material stand for 2-3 minutes to enable entrapped air, if any, to escape from the mix and then use as quickly as possible. INJECTION The grout mixture should be pumped by a positive displacement plunger type pump. Inject at slow and even pressure through the injecting nipples till refusal or when the/grout oozes out from nipple immediately adjacent to or above the one being injected.

SUNKEM PLAST R

WATER REDUCING CUM SET RETRADING CONCRETE ADMIXTURE SUNKEM PLAST - R is a high performance water reducing cum set retarding concrete admixture based on selected organic polyemers which when added delay the initial setting properties of concrete and a simultaneously increassing workability. Slow dispersion of heat evolved by by addition of SUNKEM PLAST - R prevents cold joints in mass concreting and is very useful for transportation or placing of concrete for longer distance and or to retain there workability of concrete particularly in hot weather conditions. ADVANTAGE The addition of SUNKEM PLAST - R provides the following beneficial properties. * Increase setting time at elevated temperature. * Improve workability and flow properties without increasing water. * Prevent rapid slump loss (higher retention) * Increase ultimate strength without addition of cement content or loss of workability. * Reduce segregation, bleeding shrinkage or creep. * Increase ultimate strength without addition of cement content or loss of workability. * Reduce segregation, bleeding shrinkage or creep. * Avoid cold joints thus monolithic concrete texture. * Produce a highly impermeable concrete structure for a permanent protection from water ingress. USES * Ready mix concrete manufacturing units. * Transportation of concrete to longer distance or delayed placing. * Chimneys, High rise buildings, Using slip form shutters, Towers. * All structural, concrete placing at elevated temperature. * Mass concrete pours to avoid cold joints. * Offshore construction and pilling works.

SUNKEM PLAST A

WATER REDUCING CUM SET ACCLERATING CONCRETE ADMIXTURE SUNKEM PLAST - A is a highly effective plasticizer cum set accelerator which accelerate the setting time and strength of the admixed concrete or mortar hereby providing multiple advantages. It is an high performance and an unique combination of selected organic polymers and inorganic component, free from chloride and provide substantial amount of water reduction and promoting high early and ultimate strength even in coolest weather and or under water conditions. ADVANTAGE As a plasticizer * Produce high early strength coupled with improved workability without incurring substantial extra cost. * Improves the common properties of the mix, reduces the segregation and bleeding. * Improves durability by increasing density and lowering permeability. As an accelerator, * Provides acceleration in setting time, by virtue of which casting and policing is made easier, particularly in cold weather and underwater concreting. * Suitable for all types of precast & Prestressed concrete works, where early release and re-utilization of form work is essential to economical and speedy production. USES * Concrete laid at normal or bellow climatic temperature. * Suitable for use any grade of concrete below or above ground level specially in under water concreting. * Suitable for use in Prestressed structures, precast job like Block-Bricks, Cement Tiles, Manholes, Pipes or Electric poles * Manufacturing units. * Emergency repairing where early strength development is essential like Railway Bridge, Road culverts, Public utility structures etc.
