Beyond the Sorptivity: Definition, Measurement, and Properties of the Secondary Sorptivity [PDF]
Journal of Materials in Civil Engineering, 2018 Capillary imbibition in brick, stone and concrete occurs in two stages. The primary process, which occurs in the standard test to measure sorptivity, is a spontaneous imbibition in which air is displaced by the invading liquid (usally water). In primary imbibition, the displacement of air is incomplete, and some air is trapped. The residual air content

Absorption and Sorptivity of Cover Concrete [PDF]
Journal of Materials in Civil Engineering, 1997 The absorption characteristics and sorptivity of cover concrete obtained by the initial surface absorption test (ISAT), the covercrete absorption test (CAT), and the sorptivity test have been studied and compared. Two types of concrete, namely ordinary portland cement (OPC) control and low water concrete (LWC) of grade 35 have been tested.

Spanish Journal of Agricultural Research, 2014 Knowledge of infiltration characteristics is useful in hydrological studies of agricultural soils. Soil hydraulic parameters such as steady infiltration rate, sorptivity, and transmissivity can exhibit appreciable spatial variability. The main objectives

Investigation on Properties of Reactive Powder Concrete with Automobile Grinding Steel Waste as Fine Aggregate [PDF]
E3S Web of Conferences, 2021 High strength concrete is seldom used in normal construction practice due to its high cost and difficulties in achieving the desired design strength. This paper gives an insight on using waste material which has been disposed in lands as a sustainable ...
