case study on vacuum dewatering concrete in pdf

A high quality concrete floor or pavement requires not only to be level but it should also have high wear resistance, high compressive strength, reduced shrinkage and minimum water permeability.
Vacuum dewatered concrete, popularly know tremix in India, is developed by Tremix, Sweden. It is a system for laying high quality concrete floors with superior cost-effectiveness. The key to the use of this method is the dewatering of concrete by vacuum process. Immediately after placing and compaction, ....etc

Abstract

Results of a 2-yr study of cause-effect relationships involved in roughness of concrete pavements are reported. Data were derived both from analog traces obtained with a profilograph in each wheelpath of randomly selected pavements within hours after placement, and from qualitative observations of placement methods. Construction sampled consisted of 184 sections of one - and - two - lane pavements built under 62 different contracts with seven different form-type finishing machines and three different slip-form pavers. Statistical anal ....etc

A washing machine (laundry machine, clothes washer, or washer) is a machine used to wash laundry, such as clothing and sheets. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids, and is performed by specialist businesses) or ultrasonic cleaners.A washing machine is a machine that washes dirty clothes. It contains a barrel into which the clothes are placed. This barrel is filled with water, and then rotated very quickly to make the water remove dirt from the clothes. Most wash ....etc

Electroosmotic flow (or electro-osmotic flow, often abbreviated EOF; synonymous with electroosmosis orelectroendosmosis) is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, microchannel, or any other fluid conduit. Because electroosmotic velocities are independent of conduit size, as long as the electrical double layer is much smaller than the characteristic length scale of the channel, electroosmotic flow is most significant when in small channels. Electroosmotic flow is an essential comp ....etc

Water-cement ratio is detrimental for concrete. We always try to restrict the water-cement ratio in order to achieve higher strength. The chemical reaction of cement with water requires a water-cement ratio of less than 0.38, whereas the adopted water-cement ratio is much more than that mainly because of the requirement of workability. Workability is also important for concrete, so it can be placed in the formwork easily without honeycombing. ....etc
