The way to Test Water Absorption in a Paver Block
Paver blocks are not impervious to water, and in order to bond well with mortar, they have to be able to absorb some water. The first rate of water absorption is measured in grams and can be utilized to ascertain whether or not pavers must be soaked in water before laying. Assessing a paver’s water absorption is a task that needs no structural engineering or building abilities and can be accomplished with nothing but easily available household items.
Make sure that the block to be examined is clean and free of debris and dust by brushing it nicely with a household cleaning brush.
Switch on a set of electronic kitchen scales, pick the metric units option and check that the reading on the display is zero. If necessary, adjust according to the manufacturer’s instructions, usually by pressing a calibration button or changing the scales off and on again to achieve a zero reading.
Place the test block on the scales and then record the weight as just as you can.
Place the same block in a pail of water, therefore it’s partly submerged, and leave it there for one moment.
Remove the block from the water and then remove any surface water by tapping it dry with a towel.
Place the block on the scales and then record the weight , again measuring as just as possible.
Deduct the original “dry” weight figure out of the last “wet” weight figure to determine the weight of water absorbed by the block during the test interval. For instance, if the dry block weighed 1,000 grams and the wet block weighed 1,050 grams, then the block consumed 50 grams of water.
