  • the present invention relates to a process of fabricating fiber reinforced concrete masonry units made from a mixture of coarse aggregate, fine aggregate, cement, predetermined structural fibers, and water.
  • U.S. Patent 5,640,825 entitled “METHOD OF STRENGTHENING MASONRY AND CONCRETE WALLS WITH COMPOSITE STRAP AND HIGH STRENGTH RANDOM FIBERS”, discloses a method of strengthening a wall which includes the step of preparing a portion of a surface of a wall to be strengthened by cleaning the surface and providing a plurality of straps of flexible nonmetallic fiber composite material to the wall portion along at least lengthwise portions of the straps and opposite end portions thereof by epoxy bonding the straps onto the surface.
  • Lockwood U.S. Patent 5,894,003 entitled AMETHOD OF STRENGTHENING AN EXISTING REINFORCED CONCRETE MEMBER", discloses the step of parallel space grooves being cut within the surface of an existing reinforced concrete member in the direction of bending and at locations where existing tensile reinforcing is inadequate, and positioning elongated reinforcing elements, such as composite rods with continuous carbon fibers within the grooves.
  • the present invention provides a novel and unique process of fabricating fiber reinforced concrete masonry units comprising the steps of: forming a mixture of coarse aggregate, fine aggregate, cement, predetermined fibers, and water; and feeding said mixture into concrete masonry unit molds to form in said concrete masonry molds said fiber-reinforced concrete masonry units.
  • the present invention also provides novel and unique products produced in accordance with the aforesaid method.
  • the present invention also provides a novel and unique fiber reinforced concrete masonry unit, comprising: coarse aggregate being present in a weight percent of approximately 22%-28%; fine aggregate being present in a weight percent of approximately 57%-59%; cement being present in a weight percent of approximately 6%-9%; and synthetic structural fibers in the form of a blend of coarse monofilament self-fibrillating polypropylene/polyethylene material being present in a weight percent of approximately 0.01 %-0.03%
  • a primary object of the present invention is to achieve a simple and inexpensive way to increase the structural integrity of individual concrete masonry units and to increase the overall strength and integrity of buildings and other structures formed with such individual concrete masonry units.
  • Another object of the present invention is to provide a process as described hereinabove, wherein the predetermined fibers comprise synthetic structural fibers which preferably, but not necessarily, comprise a blend of coarse monofilament, self-fibrillating polypropylene/polyethylene material.
  • the present invention can best be understood by the description of the following procedure for making the novel fiber reinforced concrete masonry units, and the test results of same.
  • the first batch was a control batch representing concrete masonry units made and produced in accordance with conventional techniques.
  • a second batch, comprising the inventive fiber reinforced concrete masonry units was made and had the predetermined fibers added therein. Preferably, but not necessarily, the fibers were added or dosed at the rate of 0.5 pounds per 1 8 cubic feet of mixture.
  • the size of the batches will vary depending on the size of the producer's mixers and how many units are to be produced at once.
  • the fiber dose will vary based on the outcome desired to achieved from the product. For example, adding more fibers to an extent will increase the unit's durability and benefits.
  • control mixture yielding 1 8 cubic feet of same, was formed by mixing together 594 pounds of coarse aggregate, 1 ,395 pounds of fine aggregate, 160 pounds of cement (such as Lafarge Type 1 ) and 7.8 gallons of water.
  • the mixture for the present invention was obtained by mixing together 530 pounds of coarse aggregate, 1 ,297 pounds of fine aggregate, 1 60 pounds of cement (such as Lafarge Type 1 ), 6.22. gallons of water, and 1 /2 pound of fiber.
  • the predetermined fibers comprised synthetic structural fibers, such as, for example, a blend of coarse monofilament, self— fibrillating polypropylene/polyethylene fibers.
  • synthetic structural fibers such as, for example, a blend of coarse monofilament, self— fibrillating polypropylene/polyethylene fibers.
  • such a fiber is produced by the Euclid Chemical Company of Cleveland, Ohio under the name of "TUF-STRAND SF".
  • the concrete masonry units for compression tests were "in compliance with ASTM C-140". Between the two batches for one-day compressive strength, there was an increase of about 101 PSI in the blocks that had fibers in them compared to the control units.
  • the control units and the fiber- re info reed units were also tested for impact resistance.
  • the fiber- re info reed concrete masonry units performed between two to three times better than the conventional block when subjected o an impacting force.
  • the control group and the fiber-reinforced group were subjected to water absorption tests.
  • the fiber-reinforced concrete masonry units were less permeable, holding out more water than the control blocks.
  • the fiber-reinforced blocks absorbed less water, as much as half a pound per cubic foot less than the control block.
  • the blocks from the different batches were also subjected to a water permeability test.
  • the units with fiber-reinforcement were less permeable, holding out more water than the control blocks.
  • the top of the fiber-reinforced concrete masonry units have fibers which stick out of the tops. If desired, this can be overcome by either cutting the fibers off or melting them down to the surface by using heat. However, no fixing may be necessary or desirable at all.
  • the fibers sticking out of the top hold the possibility of increasing the bond strength between individual units in the wall from one unit to the next, making the wall more stable and structurally sound.
  • the present invention also provides for the fibers to be made of: organic materials; new types of material which equal the strength and durability of current fibers; or composite carbon and/or steel.
  • the novel features and advantages of the present invention can be obtained by varying the individual components and amount of components in the mixture for forming the concrete masonry units.
  • the weight percentages of the various components of the fiber-reinforced concrete masonry units mixtures may be as follows: 22-28% coarse aggregate; 57-69% fine aggregate; 6-9% cement; 2-3 % water; and 0.01 -0.03% fiber.
  • the above-mentioned dosages will vary depending upon a different scenarios, e.g., the types of units being made (lightweight or heavy weight); the strengths and effects to be achieved by the units will also affect the dosages of the aggregates, based on if the units are to possess high strengths, high water retention, low permeability, etc. Also, the dosage rates will vary depending on geographic location of producers and materials available to the producers from local soil sediments. The mix design quantities vary depending on the requirements of the producers' local materials, e.g., a producer using material in California will have different dosages and types of materials to make masonry units than a producer who in Michigan or in Florida.
