Webinar Description:
This webinar 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. The
webinar will cover an overview of how codes and specifications differ
relative to concrete construction.

managing programs of NRMCA Research, Engineering and Standards Committee and
the NRMCA P2P Steering Committee, coordinate and report on some of the
Association’s research studies, provide information to the membership and
others, coordinate and administer NRMCA technical training programs, and
develop NRMCA technical publications. Colin manages the NRMCA certification
programs for Ready Mixed Concrete Production Facilities, Concrete
Technologists and Pervious Concrete Contractors
Colin has been with NRMCA since 1991.
Colin holds a Bachelor of Engineering Degree in Civil Engineering from
Mysore University in India. He received a Masters of Science Degree from
Northeastern University in Boston and a Ph.D. from Purdue University in West
Lafayette, Indiana. He has published several papers as a result of his
research work at Purdue and NRMCA.
Colin is an active member on various committees of the American Society for
Testing and Materials (ASTM) and the American Concrete Institute (ACI). He
is a member of the American Society of Civil Engineers (ASCE) and
participates in the technical committee work of the Transportation Research
Board (TRB). Colin has been a member of technical task groups and research
panels of AASHTO and FHWA. He is a registered professional engineer in the
State of Maryland.
On ACI, Colin is a member of ACI Committees 318 (Building Code), 301
(Specifications), 214 (strength testing), 211 (mixture proportioning), and
educational committee E701 on concrete materials. He serves as the recording
secretary of ACI 301. He is a Fellow of the ACI.
On ASTM, Colin is a member of ASTM Subcommittees 09.94 data analysis, 09.96
(CCRL), 09.40 (ready mixed concrete), 09.60 (fresh concrete tests), 09.61
(strength testing), 01.10 (cement specifications) and many others. He serves
as recording secretary for 09.60 and 09.40.
He serves as NRMCA’s representative on the FHWA Concrete Pavement Technology
Program Engineering ETG (Task 65), Performance Specifications ETG, Mixture
Optimization ETG, PCA’s Product Standards and Technology Subcommittee and
other technical committees as pertinent to the goals of the NRMCA.
Colin has coordinated and reported on research activities at NRMCA related
to measurement of water content in fresh concrete, use of wash water in
ready mixed concrete, effects of reuse of returned concrete on concrete
properties, testing high strength concrete and cores, alkali silica
reactivity tests, reuse of returned concrete, maturity of high volume fly
ash concrete, concrete durability research and several smaller research
projects.
