The new NRMCA producer quality certification raises the bar,
establishes credibility in the marketplace and it is well established
that improved quality reduces costs. The quality certification focuses
on management commitment to quality, qualified personnel, properly
maintained production facilities (main focus of the NRMCA plant
certification), monitoring quality of concrete materials and the
produced product and measurement systems.
This video is designed to provide an overview of the NRMCA plant
inspection process which is addressed in the NRMCA Plant Inspector
Guide. It is intended for ready mixed producers and plant inspectors who
perform inspections for the NRMCA Plant Certification Program.
Fly Ash Concrete Presented by:
Karthik Obla 1.5 hours duration | Pub Code: PPV_OFAC
What is the right amount of fly ash to use in concrete? Is as much as
possible the right answer? What does the Code say? What do the
specifications say? What happens to concrete performance with increasing
fly ash? What about cost savings? What is the producer’s perspective?
What is the engineer’s perspective?
This video will provide a concise overview of responsibilities of
ready mixed concrete producers and other parties as addressed in
industry standards such as ACI 318, Building Code for Structural
Concrete, ACI 301, Specifications for Structural Concrete and ASTM C94,
Specification for Ready Mixed Concrete. The items include provisions for
strength, properties of fresh concrete and delivery.
This video will cover the
fundamental statistics and associated provisions for submittals,
acceptance and referee testing of concrete strength. It will cover
factors that influence measured concrete strength and the standards that
govern strength testing.
Every year, it is estimated that 2% to 10% (average of 5%) of the
estimated 455 million cubic yards of ready mixed concrete produced in
the U.S. (est. 2006) is returned to the concrete plant. Also it is
estimated that 150 gallons of water is used to wash out a ready mixed
concrete truck every day. There is also a lot of process water generated
at ready mixed plants, including stormwater which MUST BE treated as
process water if allowed to commingle with process water. A ready mixed
concrete producer SHOULD handle the returned concrete and water from
concreting operations at a plant in a sustainable commercially viable
This video will discuss the various options of handling returned
concrete – in particular the research work conducted at NRMCA on the use
of crushed concrete aggregates for new concrete. It will also discuss
the options in reusing water from concrete production operations.
Technical and operational issues will be covered.
