- is a superplasticizing, high range water-reducing and retarding admixture
? ASTM C-494 Type G
This is the choice where retardation of set is necessary. It can be used in hot weather concreting, long distance hauling of ready mixed concrete, and when truck mixers are made to wait in a queue for a long time before pouring.
PRIMEPLAST R1-10 is an admixture for concrete mixes, is used for superplasticizing and improving properties of concrete such as: slump, workability, placeability, pumpability, flowability, strength, durability, permeability, bond to reinforcing steel, etc. While some terms are at times interchangeable, it is because one property usually leads to the next as will be illustrated later.
PRIMEPLAST R1-10 reduces the water demand of concrete mixes. If, for example, normal concrete would require a 0.6 water-to-cement ratio (W/C) and a slump of 4 inches, by using PRIMEPLAST, the W/C can be reduced up to 0.3 (depending on dosage and other factors which can be determined in trial mixes), and the slump will remain at 4 inches. Such reduction of W/C results into a higher compressive strength. (Compressive strength is inversely proportional to W/C).
PRIMEPLAST R1-10 increases the slump of concrete. If a concrete mix has a slump of 2 inches, adding PRIMEPLAST R1-10 to this mix will improve the slump to 4 to 6 or 8 inches depending on the amount added. Because PRIMEPLAST R1-10 can impart high slumps, concrete will flow like liquid. At this liquid state, concrete becomes easier to handle. Some of the advantages are:
IT PUMPS MORE EASILY
IT IS PLACED MORE EASILY
IT CONSOLIDATES MORE EASILY
IT FINISHES MORE EASILY
IT HAS MORE UNIFORM STRENGTH
Such positive properties equate to savings for the user of PRIMEPLAST R1-10 . Fluid pumpability translates to less power consumption. Pumping concrete to high rise levels will be like pumping grease. And because liquid seeks its own level, fluid concrete fills forms more compactly and therefore prevents the formation of honeycombs. Thus, the time in placing, consolidating and finishing becomes much less, and therefore, labor is easier and cheaper.
Provided concrete mixtures are properly proportioned, concrete made to flow with PRIMEPLAST R1-10 becomes extremely workable without bleeding and segregation.
PRIMEPLAST R1-10 contains no calcium chloride and therefore, has no deleterious effect on steel. It is purely organic in nature with anionic sites in its molecule.
PRIMEPLAST R1-10 is a necessary ingredient when designing high strength and high performance concrete.
PRIMEPLAST FLOWING CONCRETE finds practical use where reinforcement is closely spaced. Such locations make consolidation difficult unless concrete is made to flow with PRIMEPLAST.
PRIMEPLAST FLOWING CONCRETE is the answer where concrete has to be pumped to higher levels or long distances. Pumping pressure is drastically reduced and the rate of placement is improved.
PRIMEPLAST FLOWING CONCRETE is desirable in massive placements. The cement content can be lowered and in turn, heat development will be minimized. The low W/C ratio will reduce shrinkage and consequently reduce cracking, and improve both tightness and permeability.
PRIMEPLAST R1-10 is used for making piles, pre-cast and post-tensioned concrete. A high early strength type is employed in order to release forms and molds faster.
Incompatibility is indicated when a concrete mix becomes agglomerated as the admixture is added. Lumps of concrete result instead of a uniformly distributed fluid mass.
PRIMEPLAST R1-10 has been tested with all brands of cement in the Philippines and it has not encountered any incompatibility. Incompatibility usually occurs when some calcium compounds show limited solubility in water. PRIMEPLAST R1-10 is formulated that it helps chelate certain positive ions present in concrete mixtures holding such ions into a complex, and suspended to cause no harm.
Generally, use (1% on weight of cement) of PRIMEPLAST R1-10 per bag of cement. Additional dosages should be used when delays in pouring occur and the required slump has not been maintained. Two additional dosages are safe and do not affect the compressive strength.
PRIMEPLAST R1-10 Has a specific gravity of 1.18 with a variance of 0.01.
