Abstract
The present invention relates to an improved concrete additive product comprising synthetic concrete reinforcing fibers packaged in a closed paper package, whereby under the influence of mechanical action in a concrete mixer, the packaging material disintegrates and the fibers are uniformly distributed throughout the fresh concrete mixture. The synthetic fibers may additionally be coated with a dispersant. The present invention also relates to the methods of using the above improved concrete additive product.
Claims49
A method for providing a relatively uniform distribution of fibers throughout fresh concrete, comprising the steps of:
- placing one or more closed non-soluble paper packages into fresh concrete, said packages containing a cumulatively effective amount of fibers operative to reinforce the concrete when set;
- and
- agitating the fresh concrete to cause the packaging material to disintegrate and dispense said fibers uniformly throughout the fresh concrete.
A method for uniformly distributing fibers throughout fresh concrete, comprising the steps of:
- (a) placing a closed non-soluble paper package containing an effective amount of fibers directly into fresh concrete, said fibers operative to reinforce the concrete when set;
- and
- (b) mixing the fresh concrete of step (a) in a batch type mixer for sufficient time to cause the package to disintegrate and uniformly distribute said fibers throughout the fresh concrete.
A concrete admixture package, comprising:
- synthetic fibers operative to dispense throughout a volume of fresh concrete upon agitation of the concrete and to reinforce the concrete when set, and
- a closed non-soluble paper bag enclosing said fibers, said bag operative to disintegrate in agitated fresh concrete and uniformly distribute said fibers throughout the fresh concrete.
A method for providing a relatively uniform distribution of fibers throughout fresh concrete, comprising the steps of:
- placing one or more closed non-water-soluble paper packages into fresh concrete, said packages containing a cumulatively effective amount of fibers operative to reinforce the concrete when set;
- and
- agitating the fresh concrete to cause the packaging material to disintegrate by fragmenting into pieces which are not detrimental to the properties of the finished concrete and to dispense said fibers uniformly throughout the fresh concrete.
A concrete admixture package, comprising:
- synthetic fibers operative to dispense throughout a volume of fresh concrete upon agitation of the concrete and to reinforce the concrete when set, and
- a closed non-water-soluble paper bag enclosing said synthetic fibers, said bag operative when agitated in fresh concrete to disintegrate by fragmenting into pieces which are not detrimental to the properties of the finished concrete and to result thereby in the uniform distribution of said fibers throughout the fresh concrete.
