CONSPLAST PC-L3 is a low-range polycarboxylic ether based retarding super plasticizer. CONSPLAST PC-L3 greatly improves cement dispersion that makes it possible to manufacture flowable concrete requiring no compaction at very low water/cement ratio. The mechanism is based on steric hindrance effect which stabilizes cement particle’s capacity to separate and disperse. Mainly used where high slump retention property is required.
FEATURES / ADVANTAGES
• It facilitates high early and long term strength gains with super slump retention property at very low water cement ratio.
• High level of fluidity that can be poured and placed by gravity avoiding the need of vibration.
• Increased early and ultimate compressive strengths.
• Increased flexural strength.
• It increases the strength of the concrete due to water reduction property.
• It reduces shrinkage and permeability of hardened concrete.
• It can be used even for flyash and slag cement concrete.
• It eliminates formation of cold joints between subsequent pours in mass of structural concrete.
AREA OF APPLICATIONS
• Long distance transporting.
• For low water / binder ratio mixes.
• Readymix concrete.
• Piling concrete.
• High performance concrete for good durability
• Very high strength concrete
• Precast concrete
• Normal Dosage range is 0.4 to 1.2 % by weight of cementitious materials including flyash, GGBS & microsilica.
• The optimum dosage to meet the specific requirement should always be determined by conducting trial mixes using the materials and conditions that will be experience in use. Because of variations in job conditions, concrete materials and climatic conditions dosage rates may vary in such cases.
• CONSPLAST PC-L3 ensures that concrete remains workable for approximate 3 hours at 250C. Workability loss is dependent on temperature, type of cement, nature of aggregates, the method of transport and initial workability. It is strongly recommended that concrete should be properly cured particularly in hot and dry climates.
EFFECTS OF OVERDOSAGE
• Delay of initial & final setting of concrete.
• Increase in plastic shrinkage.
• Increase in air entrainment.
• Severe bleed & segregation of mix.
