where t0.5 is the half-response time, the time required for fully exposed grain to reach a moisture ratio of 0.5 under the drying air conditions employed. It can be calculated from the thin layer drying equations as in Equation 1 with MR assigned a value of 0.5.

Drying response of lime mortar joints in granite masonry

Jun 10, 2019 The walls in which mortar joints reach their 0 state or below show that the granite units also reach their initial value (Fig. 5b, walls 1 and 4), whereas walls in which mortar joints do not dry out as much (Fig. 5b, walls 2, 3 and 5), experience a granite unit that remains wetter (Fig. 5b’).

Water Absorption of Aggregate CivilWeb Spreadsheets

The water absorption value for aggregates describes the percentage increase in weight between the dry aggregate and the saturated aggregate. Therefore the absorption value is the amount of water which the aggregates are able to hold. The absorption value can be ascertained using the water absorption test described in BS EN 1097-6 and should ...
