Project Planning Phase Services

With Project Planning Phase, we aim to build the quality of concrete ingredients upfront into the client’s project to improve the life of structures and be able to reduce the maintenance costs. We accomplish this using various aspects of concrete analysis, sourcing and qualifying the planning stages.

We assist our clients in various aspects of concrete analysis, sourcing and qualifying during their projects planning stages.

Our focus is to maximize the lifespan of your project through project planning phase services.

We determine which materials are best for your structure. We place special consideration on sources, consistency of material, and overall durability. For capital projects we ensure materials are compliant to the project’s specifications and durability requirements.

Sourcing

Sources of good aggregates and cements are identified and monitored

Sampling

Samples are collected for evaluation to assure quality

Analysis

Granite evaluation by petrographic analysis

Testing

Petrographic test to identify potential alkali-silica reactivity

Cement

C3S helps its clients to evaluate cement on capital projects for compliance to project specifications and durability requirements.

It is far less expensive to plan for quality than it is to remediate problems down the road.

Here are two examples of problems that could have been prevented by utilizing C3S services during the project planning phase.

 

examples of problems that could have been prevented by utilizing C3S services during the project planning phase.

File photo from a project of three (3) year old water tank. Analysis revealed wrong choice of cement and high water cement ratio led to formation of expansive Ettringite in the concrete.

File photo from a project involving breakage of concrete coating over metal pipe. Analysis revealed the wrong choice of cement and a high void content in the concrete led to failure.

Aggregates

C3S helps its clients to evaluate aggregates on capital projects for compliance to project specifications and durability requirements.

The choice of aggregate for concrete is critical to a successful project. Trust C3S to help you identify and source the best aggregates for your project and to monitor that they are utilized exactly as specified.

aggregate testing and evaluation

Scope: To determine whether the three rock boulders to be beneficiated into aggregates are suitable for use as construction material, specifically, that it will not pose a threat of alkali-silica reaction, ASR, in concrete.

Note – Picture above shows cracks through the aggregate in one of the samples sent to us.

aggregate testing and evaluation
Scope: To determine whether the six subject sample specimens are suitable for use as construction material – to be used as aggregate in concrete.

Note – Picture above shows a representative section of Ammari 15/25 aggregate sample.

Mineral Admixtures

A section of a major highway between two major cities in Texas experienced surface defects about two years after completion. A three mile stretch had to be replaced. Samples evaluated in connection with the problem pointed to a high dosage of mineral admixture used in the affected section of the pavement.

Choice of mineral admixture (i) – to optimize concrete placement in varying weather conditions, and (ii) improve durability of hardened concrete. Examples of damage to structure due to contribution by mineral aggregate used.

Chemical Admixtures

Examples of entrained air content, mostly for long term durability of concrete, in freeze-thaw regions can adversely affect compressive strength of the concrete if in excess.

If entrained air content is below the specified amount it raises long term durability concerns, and in some instances,  affected sections of the structure may have to be replaced.

aggregate testing and evaluation

Inadvertent dosage of air entraining agent – a high air content – causes a loss in compressive strength in a concrete on a highway project.

Less than specified entrained air content for a section of a bridge deck in Vermont caused the affected section to be replaced due to long term durability considerations.
