Besides enhancing the early strength and durability of the concrete, it reduces to half the steam curing time. 50% Less Steam Curing - Two alternative concrete mixes for the same application (W/C ratio of 0.42) were evaluated. The evaluation took into account that for the mix containing SikaRapid®-1, 50% less steam curing time is needed.

During delivery of ready mixed concrete, the slump may change depending on a host of variables. However, the slump is typically known only at the batch plant or job site. This session explains the concepts used for the measurement of several properties (such as workability and volume) of fresh concrete directly in the drum of the concrete truck.

Water discharged into the mixer is the main but not the only source of mixing water in concrete: During hot-weather concreting, ice may be used as part of the mixing water to cool the concrete. The ice should be completely melted by the time mixing is completed.
purpose, the structure must be provided with rising wings, high enough to concentrate the flow in case of overflow to avoid lateral erosion. Germany (Bavaria) Peter Wagner presented a recent study held in Bavaria to assess the functioning of different structures of woody debris trap/ bedload transport regulation.

The concrete is generally in com-p r ession, so cracking is unlikely except from rough han-dling, and the concrete that is used is usually of higher s t r ength so it can withstand the pre s t ressing opera t i o n . Due to the special manufacturing pro c e s s , in which the poles are spun at high speeds, they have a smoother sur-
Self loading concrete mixer is the combination of concrete mixer truck and cement mixer, which can automatically feed, measure, mix and discharge concrete mixture at 270 degree.It is not exaggerated to say that just using a high efficient self loading concrete mixers for sale, one driver and one worker could complete the concrete work of a whole construction project.
An alternative to plant mixing is in-place mixing. Although the mix-in-place approach does not usually result in as accurate a proportioning of the mix components as plant mixing, it is still possible to produce a high-quality PSB material using this approach.

3. Option C is a mixed option. It requires the concrete producer to select the mix proportions with the min-imum allowable cement content and compressive strength specified by the purchaser. BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer.
Wastewater Technology Fact Sheet Sequencing Batch Reactors DESCRIPTION The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged.
