Determination of moisture content in total is of key significance in the control of the nature of cement especially as for workability and quality. The measurement of the moisture content of aggregates is basically a very simple process. But it is complicated by several factors.
Workability of concrete simply means the ability to work with concrete. Fresh concrete is said to be workable if it can be easily transported, placed, compacted, and finished without any segregation. The ease of placing, compacting, and finishing of concrete in
Malcolm Bruce, a.k.a. Brucieboy to his pals in The Brew Cabin discussion forum on this website, has spent a lifetime in the concrete batching industry, advising on mixes, specifications, additives and the use of fibre reinforcement. Here, he shares his thoughts on the use of both mesh and fibre reinforcement in modern slab construction:

All of the batching is going to be done without stationary mixers, and all done manually. Does anyone have any recommendations for ratios of materials to achieve 3000psi and 4000psi concrete in these conditions? Are there any other special circumstances we need to account for while manually batching? Thank you for any help given.

If a concrete pump will be used to place concrete on site, then the concrete used in the trial batches will
Oct 28, 2013 · Concrete usually reaches 75% of the 28-day strength at seven days. If your concrete is not reaching the proper 28-day strength, I would troubleshoot each step of the process to determine why. Here are example questions you can ask: Q: Is the mix design correct? A high water-cement ratio will result in a concrete with reduced strength.

If the mixed concrete looks like the mix in step 8, it's ready to pour. Otherwise, mix in additional dry mix or water until you get the right consistency. It's tempting to just squirt water into the dry concrete mix with a hose and mix up a soupy batch of concrete. After all, it's quicker and the runny concrete is easier to pour.
Thus the aim of this paper is to define the limits and extent to which cement-based slurry water from the concrete batching plant can be recycled and totally reused for making concrete without the need for further treatment. The study focused on the effects
FINAL REPORT EVALUATION OF CONCRETE CHARACTERISTICS FOR RIGID PAVEMENTS D. S. Lane Senior Research Scientist INTRODUCTION For rigid pavements, the Virginia Department of Transportation's (VDOT) 1993 Road and Bridge Specifications (VDOT 1993) specified that the concrete have a 28-day compressive
MEASURING, MIXING, TRANSPORTING, AND PLACING CONCRETE 304R-3 The more a form is filled with the right combination of sol-ids and the less it is filled with water, the better the resulting concrete will be. Use only as much cement as is required to achieve
The electric mixing equipment is the most significant contributor to the emissions generated by concrete batching. It has been demonstrated in an internal review by a large concrete manufacturer that substantial improvements can be made to the efficiency of batching equipment by commissioning independent electrical contractors to report on the efficiency of batching equipment and making ...
mixer trucks. The concrete is mixed on the way to the site where the concrete is to be poured. At some of these plants, the concrete may also be manufactured in a central mix drum and transferred to a transport truck. Most of the remaining concrete manufactured are products cast in a factory setting.
Apr 01, 2001 · Eight samples from each batch should be taken at various times during the concrete discharge, and the properties listed above measured. A mixer can be considered adequate if the fractional variation between measurements on any of the above properties is less than 6 % to 8 % for each batch of concrete.
Oct 02, 2015 · Department of Civil Technology Written By: Ahmed Zakaria 7 Concrete mix Design Concrete mix design may be defines as the art of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength & durability as economically as possible.
Concrete slump test or slump cone test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction.

The concrete composition considered as the reference is an Ordinary Portland Concrete of 25/30 class of strength. Recycled concrete composition is the same as the reference concrete mixture. However, because of the high water absorption of recycled aggregates, water proportion was adjusted to reach the desired work ability.
Apr 10, 2014 · What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching. Below are mentioned some of important points to remember before adopting volume batching method in …
The various concrete mixes collected from Case 1, 2, 3 and 4 have been given a specific designation based on the grade of concrete, slot / batch and specific case from where the batch has been collected. These designations prove to be very useful in referring the concerned mixes during the analysis.
