Batching, Mixing, Transporting, and Handling Concrete

Influence of mixing protocol on fresh and hardened

Nov 15, 2015 · A concrete mixer as shown in Fig. 2 (also commonly called a cement mixer) is a device that homogeneously combines cement with aggregates such as sand or gravel and water. A typical concrete mixer uses a revolving drum to mix the components. Internal blades are arranged in such a manner to lift and tumble the ingredients and direct the concrete into the circulatory path.

How to select MCB / MCCB - Controlmakers

Jul 27, 2017 · Example: what should we select MCB or MCCB for current carrying capacity 100A and breaking capacity 15KA and cost is a not main criteria. For this rating both MCB and MCCB are available so we should consider application and other facilities to choose MCB or MCCB. If we want to use it at indoor purpose, having less Space and if we do not need tripping adjustment and other function or

Concrete Slump Test for Workability -Procedure and Results

Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction. The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922.

Batching, Mixing, Placing and Compaction of Concrete

Mar 18, 2017 · Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.

Quality Management Plan Guidance for Concrete used for

information about concrete material related quality assurance (QA) and quality control (QC) practices for the Bureau of Reclamation (Reclamation) construction projects with significant concrete features. It is intended to serve as a guide for developing a QMP for concrete used for construction of significant concrete features of a project.

Concrete Production - an overview | ScienceDirect Topics

Concrete production is a highly intensive energy-consuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. Sustainable technologies in maintaining concrete structures are proving to be a great challenge. Microbially induced carbonate precipitation (MICP) has developed as a novel and sustainable technique in improving the

White Paper - Self-Consolidating Concrete

Oct 15, 2015 · 1 Introduction Self-consolidating concrete (SCC) is a high-performance concrete that has been a growing commodity among the construction industry acting as an alternative to conventional concrete. While SCC was first introduced as a solution for durability, engineers and contractors have seen the added benefits, which have propelled its popularity.

Properties of Concrete - Workability, Setting, Bleeding

Mar 19, 2017 · Fresh concrete is that stage of concrete in which concrete can be moulded and it is in plastic state. This is also called "Green Concrete". Another term used to describe the state of fresh concrete is consistence, which is the ease with which concrete will flow. The transition process of changing of concrete from plastic state to hardened state.


The objective of this competition is to design a concrete mix using alternative materials with low environmental impacts while improving durability performance. b. Functional unit The functional unit is the production of one cubic meter of concrete mixture. complying with the rules mentioned in sections 2.2 and 2.3. c. System boundaries

Top 6 Important Quality Tests Of Concrete

Aug 05, 2015 · 1. Slump test before leaving the batching plant and on arrival on site. This is to determine the workability of concrete in terms of slump test. After batching the concrete, a sample of fresh concrete shall be taken to test for slump tests and the samples …

Order Batching in Warehouses by Minimizing Total Tardiness

One of the cost-intensive issues in managing warehouses is the order picking problem which deals with the retrieval of items from their storage locations in order to meet customer requests. Many solution approaches have been proposed in order to minimize traveling distance in the process of order picking. However, in practice, customer orders have to be completed by certain due dates in order

Statistical analysis of concrete transport properties

Mar 26, 2013 · The concrete mixes that were batched under laboratory conditions have a COV of less than 2 %, while the field concretes with ternary cement blends (used for bridge repairs) have a variability closer to 4 %, and the field concretes with ordinary cement (used for building construction) have a variability of about 2.5 %.


Here are some general tips to consider when selecting a . ribbon blender. Choose a level installation location. A ribbon blender is normally supplied in a floor-mounted design. This design requires the blender be bolted to a level floor made from a strong, suitable material, such as heavy-duty concrete, that can handle the weight of
