Global lab provide the art of the precise, accurate & reliable testing service accrediated by NABL for durability Test of Concrete as per BS 1881 (Part-122) : 1983 Amd-01.
30min Water Absorption Test:
This test gives a measure of resistance of concrete against the water absorption under specified condition for a period of 30min±0.5 min.
Note: If the absorption test is carried out on concrete less then 28 days old an appreciably higher value may be obtained. Conversely, the absorption at ages greater than 28 days might be appreciably less. These variations are dependent, amongst other factors, on the rate of hydration of the cement.
