MODELING THE DEGREE OF SATURATION ON CONCRETE STRUCTURE ...

Most concrete only partially saturated and the initial ingress of water and dissolved salt is dominated, at least initially, by capillary absorption rather than either water permeability or ion diffusions. A wide variety of water absorption test of concrete have been developed. These test measure the weight gain of a sample, volume of water

PDF Interaction of Water with Epoxy

absorption by epoxy resins are discussed. These studies show that absorption can disrupt hydrogen bonds among segments of the polymers and cause swelling of the polymer. The water absorption increases the diffusion coefficient of water within the polymer. Permanent damage to the polymer can result if water causes hydrolysis of ether linkages.

The results showed that water-cured eggshell concrete greatly improved the compressive and flexural strength of concrete, by up to 51·1% and 57·8%, respectively. The rate of water absorption of eggshell concrete was reduced by approximately 50%, as eggshell powder filled up the existing voids, making it more impermeable.

Based on an extended experimental research programme, with test on 22 different concrete mixes (traditional concrete and self-compacting concrete), the relation between water absorption by immersion and some concrete durability issues is investigated. Within these tests, accelerated carbonation and chloride migration tests are realised.

Importance of Water-Cement Ratio in Concrete

Good concrete results from a good mix design and a low w/c ratio is one but very empirical part of a good mix design. Higher the water-cement ratio means the higher quantity of water which results in dilution in cement paste. It makes poor concrete mix and increases water permeability. Thus, leads to leakage and dampness.

Water absorption is a measure of porosity of aggregates and its resistance to frost action. Higher water absorption means more pores hence aggregate will be the considered as weak. Water absorption value ranges from 0.1 – 2.0% for aggregate normally used in roads surfaces. Aggregates with water absorption up to 4.0% are acceptable in base coarse.
