- Example 5 Properties of concretes, grouts and mortars according to the invention 5.1 - Mechanical resistance
- the mechanical strength of the mortars according to the invention is measured on specimens of 4x4x16 cm 3 prismatic mortars prepared at 20 ° C. using metal molds and demolded at 24 hours. The resistance of the samples obtained is tested according to NF EN 196-1 and NF EN 12390-3.
- This pressure is equivalent to the effect of driving rain perpendicular to the surface and with a wind speed of 142.6km / h.
- This test makes it possible to know the capacity of water absorption on the surface of a material.
- the glass pipe is fixed on the material to be tested using a reversible waterproof paste.
- the difference between the level 0 and the level recorded as a function of time makes it possible to evaluate the degree of absorption of the support. To perform the test effectively, the measurements are made on three different zones for the same nature of support.
- water absorption values of the Weber HP sealing mortar are 1.5 times to 7 times greater than those of the mortars of the invention, which therefore have better impermeability to water.
- the gloss values of the mortars according to the invention are measured with glossmeter (TOC Polygloss GL0030) with the reference angles 20 ° and 60 ° according to the ISO 2813 standard.
- the reference used is a polished glass plate black-tinted and non-translucent (glass type for welding mask).
- the principle of the test is to measure the angle of contact (or advanced angle) of a drop of distilled water deposited with a syringe on the surface of the test material.
- the drop a millimeter in diameter is photographed, this photograph undergoes a computer processing that will determine the outline of the drop, which will determine the contact angle formed by the drop of water on the material (and therefore the coefficient of surface tension of the latter).
- a contact angle in the range of 0 ° to 89 ° generally defines a hydrophilic material, while an angle greater than 90 ° defines a hydrophobic material (and even "super hydrophobic" when the angle is greater than 150 °).
