Fast drying concrete has been used for the floors of buildings in Finland for the last nine years. By using high quality concrete the risk of mould growth can be decreased not only during the building process but also during the occupancy of the building. The fast strength development of ...
No matter your role in the building process, it pays to learn issues, standards, & methods of proper concrete drying times & concrete moisture levels.
This paper presents a design-office procedure for calculating the shrinkage and creep of concrete using the information available at design, namely, the 28-day specified concrete strength, the concrete strength at loading, element size, and the relative humidity. The method includes strength developmen...
Solar drying is used for both steps. The grain or flour is dried on polythene sheets, either directly on a concrete floor or on long tables made of wooden slats. View chapterExplore book Related terms: Carotenoid Microwave Drying Moisture Freeze Drying Heat Pump Solar Energy Solar Radiation ...
food preservation,methods of preparing food so that it can be stored for future use. Because most foods remain edible for only a brief period of time, people since the earliest ages have experimented with methods for successful food preservation. Among the products of early food conservation were...
Desiccation shrinkage of concrete and mortar induces the formation of microcracks leading to mechanical damage of concrete structures. This damage, induced by drying, can be characterized by time evolutions of the material elastic properties. The main purpose of this study is to propose an experimental...
This paper examines the influence of cyclic wetting and drying on swelling strain and swelling pressure to simulate the behavior of such rocks under heavy structures (such as building foundations) and behind the stiff support systems (such as concrete linings). Mudstone samples from Bakhtiari ...
the initial moisture intrusion. If building materials and structural assemblies are exposed to water and water vapor for extended periods, moisture will penetrate them based on the porosity of the materials. The more water they absorb, the more time, effort and expense will be required...
The controller is designed to time-dependant and/or air humidity-dependant control of the air interchange ventilators for controlled exchanges of ambient air. An independent claim is also included for a drying method for drying a concrete floor.AUMILLER FLORIAN...
This paper proposes a simple equation to evaluate the water permeation rate into concrete, based on basic information such as the mix design, curing condition, and degree of drying. Concrete specimens are cast, cut into slices of different thicknesses, and the time taken for water penetration ...
