Adjust retarding, accelerating and plasticizing admixtures accordingly.</p> <p>D.</p> <p>Verify existing conditions before starting work.</p> <p>E.</p> <p>Verify that the joints are treated according to the requirements of the waterproofing <br />manufacturer’s instructions.</p> <p>C.</p> <p>Comply with manufacturer’s product data and installation instructions.</p> <p>INSTALLATION <br />A.</p> <p>Crystalline waterproofing admixture shall be added to the concrete at the time of <br />batching at a concrete plant or to the finished mix in the ready mix truck at the job site. <br />The sequence of procedure for addition will vary according to the type of batch plant <br />operation, equipment and distance from the job site.</p> <p>B.</p> <p>Do not add bulk (bag) dry powder crystalline waterproofing admix to wet concrete mix. <br />This may cause clumping of the admix and uniform dispersion cannot be guaranteed. <br />Mix with water first, before adding to wet concrete.</p> <p>B.</p> <p>At batching plant:</p> <p>C.</p> <p>1.</p> <p>Add 4 gal. (15 L) potable water per 50 lbs. (22.7 kg) powder to the wet, empty <br />turning drum of the ready-mix truck.</p> <p>2.</p> <p>Add specified amount of powder crystalline waterproofing admix to turning <br />drum and mix the powder with the water for minimum 3 minutes to a thin <br />slurry. Assure homogenous mixing. Alternatively pre-mix the powder with water <br />to a slurry in a plastic pail and add to the wet concrete mix in the drum of the <br />ready-mix truck.</p> <p>3.</p> <p>Drive the ready-mix truck under the batch plant and add/drop the specified <br />amount of concrete mix into the ready-mix truck. Take into account the amount <br />of water contained in the crystalline slurry mix.</p> <p>4.</p> <p>Mix at least 5 minutes to assure homogenous distribution of the crystalline <br />slurry mix within the concrete.</p> <p>5.</p> <p>Carry out slump and air-content quality control at job site before pouring of <br />concrete. Prepare cylinders for concrete strength control.</p> <p>Ready-mix truck at job site: <br />1.</p> <p>Mix the crystalline powder in a plastic pail with potable water to a thin slurry <br />consistency. I.e. 50 lbs. (22.7 kg) powder to 3 gal. (12 L) water. Mix for at <br />least 3 minutes.</p> <p>2.</p> <p>Add the crystalline slurry to the wet concrete mix in the turning drum of the <br />ready-mix truck.</p> <p>03 30 00-4</p> <p>Crystalline Concrete Waterproofing Admixture</p> <p>3.</p> <p>Mix at least 5 minutes to assure homogenous distribution of the crystalline <br />slurry mix within the concrete.</p> <p>4.</p> <p>Carry out slump and air-content quality control at job site before pouring of <br />concrete. Prepare cylinders for concrete strength control.</p> <p>D.</p> <p>Precast batch plant – pan type mixer: <br />1. <br />Add the crystalline powder waterproofing to the sand and aggregate, then mix <br />thoroughly for 3 – 5 minutes before adding the Portland cement and water.</p> <p>E.</p> <p>Install concrete as per project specifications, Division 03 Sections for concrete <br />installation. <br />END OF SECTION</p> <p>03 30 00-5</p> <p>Project: ........
