SP146.M FORMULATED FROM SELECTED POLYMERS SPECIALLY DESIGNED TO ENABLE THE WATER CONTENT OF THE CONCRETE TO PERFORM MORE EFFECTIVELY. THIS EFFECT CAN BE USED TO IMPROVE WORKABILITY, TO INCREASE ULTIMATE STRENGTHS OR TO FACILITATE REDUCE THE CEMENT CONTENT WHILE SUSTAINING MIX PROPERTIES. SP112-ES HAS STRONG WORKABILITY RETENTION ON WHICH HELPS IN LONG DISTANCE AND HOT WEATHER CONCRETE DELIVERIES.
LONG DISTANCE AND HOT WEATHER CONCRETE DELIVERIES HIGH WORKABILITY & RETENTION AND RETARDATION EFFECT ARE REQUIRED
PRODUCE HIGH QUALITY CONCRETE OF IMPROVED DURABILITY
HIGHER STRENGTH WITH SAME CEMENT CONTENT. MINIMIZING SEGREGATION ON PROBLEMS BY IMPROVING COHESION. SLUMP RETENTION IMPROVED WORKABILITY REDUCES PLACING AND COMPACTION PROBLEMS. COLD JOINTS CAN BE AVOIDED BY EXTENDING INITIAL AND FINAL CONCRETE SETTING TIME. SAVING CEMENT WITHOUT AFFECTING STRENGTH. MORE DURABLE CONCRETE BY CONSIDERABLE REDUCTION ON IN PERMEABILITY. REDUCED SHRINKAGE
THE RECOMMENDED DOSAGE IS BETWEEN 0.50 – 3.00 % LITER PER 100 KG OF CEMENTITIOUS MATERIALS IN THE MIX, INCLUDING GGBFS, PFA AND MICRO SILICA.
EFFECT OF OVERDOSAGE
OVER DOSAGE OF SP146.M WILL CAUSE THE FOLLOWING: INCREASE IN RETARDATION. INCREASE IN WORKABILITY. ULTIMATE CONCRETE STRENGTH WILL NOT BE ADVERSELY AFFECTED AND WILL GENERALLY BE INCREASED IF PROPER CONCRETE CURING IS MAINTAINED.
TECHNICAL PROPERTIES @ 25C°
COLOUR: BROWN LIQUID FREEZING POINT: ≈ -2 C° SPECIFIC GRAVITY: 1.24 ± 0.02 CHLORIDE CONTENT: BS 5075 NIL AIR ENTRAINMENT: TYPICALLY, LESS THAN 2% ADDITIONAL AIR IS ENTRAINED ABOVE CONTROL MIX AT NORMAL DOSAGES
ALTHOUGH THE SETTING TIME IS DEPENDENT ON THE DOSAGE OF SP146.M, THE FOLLOWING FACTORS SHOULD BE CONSIDERED: RETARDATION IS INCREASED WITH A LOWER LEVEL OF TRICALCIUM IN THE CEMENT SPECIALLY SRC CEMENT LOWER TEMPERATURES WILL DELAY THE SETTING TIME. USING MORE THAN ONE TYPE OF ADMIXTURE IN THE SAME CONCRETE MIX COULD AFFECT THE SETTING TIME.
SUPERPLASTICIZER SP146.M
SP146.M SHOULD NOT BE PREMIXED UNDER ANY CIRCUMSTANCES WITH OTHER ADMIXTURES. THE PERFORMANCE OF THE PRODUCT WILL BE AFFECTED BY THE PRESENCE OF OTHER CHEMICAL ADMIXTURES. WE RECOMMEND PRIME CHEMICALS BE CONTACTED FOR ADVICE IN THESE CIRCUMSTANCES.
SP146.M SHOULD BE STORED IN ORIGINAL CONTAINERS OR SUITABLE CLOSED TANKS PREFERABLY AWAY FROM EXTREME TEMPERATURE. ALWAYS KEEP PRODUCT IN SHADED STORAGE. STORAGE LIFE: 12 MONTHS FROM DATE OF MANUFACTURE.
CLEAN SP146.M IMMEDIATELY BY COLD WATER.
