#Mortarless concrete block construction update

If mix becomes too thick or difficult to trowel onto surface, prepare a fresh mix. Transitional or Corner Block: The corner block is shaped to connect each adjoining row connecting and. When a block is dry stacked it will align to it’s mating block, aligning and locking each block together. If mix hardens sooner, due to warm temperature, add a small amount of water to retemper the mix. Linear Block for Continuous Wall Building: All blocks have a tongue and groove feature top and bottom.

Based on new research, The Masonry Society (TMS) has developed a guide to update the design and con-struction methodology for dry-stack concrete masonry unit (CMU) walls. Apply within 30-minutes before mix starts to harden. The materials and construction are based upon ASTM C946 18 Standard Practice for Construction of Dry-Stacked, Surface-Bonded Walls. If using a mechanical mixer, keep mixing time to a minimum to avoid damaging fibers. Next, pour the fiberglass strands from the package into the mix and stir well again to ensure the strands are dispersed. Slowly add 50 lb (22.68 Kg) of FIBERWALL Cement to the liquid, constantly mixing and stirring to “pancake” consistency. Remove the package of fiberglass strands from inside of the FIBERWALL pail. ICBs are more sustainable, low involve low production cost, and environment-friendly as. Check every third course of block for plumb and straightness.įor application over Bare, Porous Surfaces (new concrete block): To a clean mixing container, first add 2 gallons (7.5 L) of clean water. Interlocking concrete blocks (ICBs) have been recently used worldwide to be alternative conventional blocks. Fit blocks snugly and remove any burrs or appendages to ensure good tight fit between blocks. Allow mortar to set approximately 4-8 hours before stacking remaining courses of block in a running bond pattern. The Intralock System is a mortarless concrete block building system comprised of blocks with six different internal configuration that form three separate.

Set the first course of block into mortar. Use quality materials and accepted construction techniques. Pre-wet surface completely with clean water prior to and during application of FIBERWALL.įor Application on New Construction of Dry-Stacked Concrete Blocks: As noted above, ensure surface is clean. Then, repair all cracks and holes in the surface with Damtite Hydraulic Cement. It is important to also neutralize any efflorescence (white, salt deposit of alkali), mold or mildew on the surface with Damtite Concrete Cleaner Crystals mixed with clean water (safe and odorless in non-ventilated areas) or with Muriatic Acid, following instructions on the label. For Application over Existing Surfaces: Ensure surface is sound, remove any loose particles and thoroughly clean any oil, grease, forming compounds from the surface since they would inhibit good adhesion of the coating onto the surface.
