Generally, the most consistent characteristic of concrete is its aptitude to continually change, creating a need for troubleshooting. Thanks to constant variability in raw ingredients and the science of advancing a mix from design stages to a desired finish, dialing in the perfect product can be extremely frustrating and time consuming.

In addition, over-analyzing the problems can sometime create more headaches and leave you in worse shape than you were to begin with. Therefore, carefully diagnosing each individual aspect of the issue through trial and error is a good start- but you have to be practical about it.

Ultimately, bad concrete leads to loss of time, loss of money, and loss of business- leaving you stranded in Possibility of slag cement place. So- where do you start? In some instances, it can be more like brain surgery, but that is the price you pay for something as valuable and versatile as concrete.

Whether aiming to create a state-of-the-art decorative pool deck for a west coast mansion or a standard grey concrete block, problems will arise that cannot simply be ignored.

That is where troubleshooting comes into play. In reality, it is impossible to map out every unique situation or combination of concrete problems and exactly how to go about fixing them.

Factors Affecting Strength in Concrete Strength and durability are some of the most important aspects of a concrete mix. Concrete has two different types of strength rating- compressive and flexural.

The most commonly referenced, compressive strength, is measured as the resistance of concrete to axial loading at a given rate. Both are extremely dependant on several other concrete factors, including the water-to-cement ratio, age of concrete, air content, handling methods, curing techniques, and aggregate properties.

So what do you do if you have low strength? Here are a few areas to review before getting too far into diagnosing your issues. Most of the time, strength related problems lie within one of the following: Obviously, admixtures can play a great role in strength acceleration and retarding, but should not be used unless researched first.

Plenty of producers run into issues that they blame on the air and other ingredients, but sometimes the problem can lie in the batching process itself. When troubleshooting for low strengths or inconsistency, make sure the batching process is what it should be.

Personally, I deal with more cases of something going wrong in the batch process than in the mix itself.

Guide Specification for Controlled Low Strength Materials (CLSM) 4 Controlled Low Strength Material D Flow Consistency of Controlled Low Strength. FOREWORD This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft finalixed by the Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in under the title ‘Code of. In some countries, Japan in particular, there are even standards for the use of slag as a concrete aggregate. In Republic of Croatia there are two slag landfills, named in this paper as landfill 1 and landfill 2, which are both landfills of air cooled steel slag—slag that originates from steel production in .

A concrete mix is a never constant because materials are always changing, but mixes can be dialed in to be extremely consistent in monitored correctly. During the batching process, there are several practices that can help keep your mix as consistent as possible.

Correcting batch water for moisture contents and implementing the correct timing sequences for adding materials and admixtures is extremely important. If not performed properly, the mix can turn into a disaster. Batch scales must be accurate if you want an accurate mix.

Calibration every 6 months is recommended. For ready mix producers, this can be a huge problem.Sigma Test & Research Center is providing facilities of testing in various fields like building material testing services, lab for building material testing, concrete testing, concrete testing lab, building material testing laboratory, house testing lab solutions and services, design and plan assessment lab, building material quality assurance, building material test, cement testing, aggregate.

The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing, when added to concrete improves its properties such as workability. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement.

It is a recovered industrial by-product of an iron blast furnace. possibility of utilizing Blast Furnace Slag (BFS) and Limestone powder (LP) as a cement substitute in concrete, in order to reduce environmental problems due to manufacturing of cement.

The joint study aims to utilise the copper slag as raw mix component in the manufacture of Ordinary Portland Cement (OPC) and as a blending material for Portland Slag Cement (PSC).

Hence while designing the raw mixes, every effort was made to keep the level of utilisation of copper slag to the maximum possible extent.
