In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured, and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure. ....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

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

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

INTRODUCTION TO RCC FILLER SLAB

Filler slab technology is a simple and a very innovative technology for a slab construction.

The reason why, concrete and steel are used together to construct RCC slab, is in their individual properties as separate building materials and their individual limitation. Concrete is good in taking compression and steel is good in tension. Thus RCC slab is a product which resists both compression as well as tensile.

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
