11 Best Method for Transportation of Concrete
Feb 08, 2019 · 09. Tremie. Tremie is the most common method for underwater transportation of concrete, tremie pipe is used for that. This word "tremie" is derived after the French word hopper. A tremie pipe is a pipe having a diameter of about 20 cm capable of easy coupling for an increase or decrease of length.
Moisture Testing Methods for Concrete Floors
Prior to applying any flooring layer onto a substrate, the preparation should be carefully taken. One of the evaluation criteria is moisture content. Below are some testing methods to measure the moisture value for concrete or cementitious screed floors. Carbide method The calcium carbide method uses the reactivity of calcium carbide with water.
Testing Methods
Air Test Method. Block the ends of the pipe, including any branches, using sealed, expanding stoppers. Fill a Utube manometer with water to the correct level, ensuring that there are no trapped air bubbles in the water. Connect the manometer to the appropriate port of one of the stoppers. Increase the pressure in the pipe until a pressure of ...
ASTM International
Nov 01, 2008 · These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight.
Corrosion Resistance of Concrete
The test also has been shown to have a somewhat lower variability than the RCPT (Hooton 2001). A more rapid test for permeability than the RCPT was developed by Florida's Department of Transportation in 2004. This procedure uses the Werner probe array method for testing resistivity of concrete .
Field Density Test (FDT) 7 Methods and their Comparison ...
Aug 30, 2018 · Roller compacted concrete is actually a hard slump low strength concrete that is poured in layers and compacted by vibratory rollers. This is low permeable concrete that is usually used around the banks of water reservoirs. In this concrete the compaction is also tested by fdt usually sand replacement method. What is FDD test?
Test Methods for Resistance of Concrete to Sulfate Attack ...
Sep 20, 2012 · Test methods such as ASTM C452 (2006) and the ChatelierAnstett test use a mixture of cement and gypsum. Since in this case the sulfate source is loed internally, no more time is needed for sulfate ingress. With these test methods results are obtained after 2 weeks, but the attack mechanism no longer represents field conditions in a ...
