Alaska Civil 24 PDH Discount Package 2

This online engineering PDH course provides guidance on details of concrete curing practice as they pertain to construction of Portland cement concrete pavements. It is organized around the major events in curing pavements: curing immediately after placement (initial curing), curing during the period after final finishing (final curing), and termination of curing and evaluation of effectiveness of curing.

 

Curing has long been recognized as an important process in constructing durable concrete pavements. Proper curing allows the concrete to develop its potential strength and durability. Inadequate curing can result in surface damage in the form of plastic shrinkage cracking, spalling, and erosion of paste. Since many variables influence the choice of curing materials and when and how to apply curing, the material presented places particular emphasis on attention to details with respect to moisture retention and concrete temperature control.

 

This 5 PDH  online  course is applicable to civil, structural and geotechnical engineers, as well as design and construction personnel involved with the design and installation of concrete pavements.

This online engineering PDH course provides information and guidance on the use of RCC in dams and other civil works structures. Elements discussed include investigation and selection of materials, mixture proportioning, design and construction considerations, construction equipment and techniques, inspection, and performance.

 

The American Concrete Institute (ACI) defines roller-compacted concrete (RCC) as "concrete compacted by roller compaction; concrete that, in its unhardened state, will support a roller while being compacted." Properties of hardened RCC can be similar to those of conventionally placed concrete. However, RCC can also be made with hardened properties that are outside the range of typical properties of conventionally placed concrete. The term "roller compaction" is also defined by ACI as "a process for compacting concrete using a roller, often a vibrating roller."

 

RCC may be considered for application where no-slump concrete can be transported, placed, and compacted using earth and rock-fill construction equipment. Ideal RCC projects will involve large placement areas, little or no reinforcement, and little or no embedded metal work or other discontinuities such as piles. Application of RCC should be considered when it is economically competitive with other construction methods. It may be considered in lieu of gabions or riprap for bank protection, especially in those areas where riprap is scarce. It may be considered for large work pads, aprons, or paved areas, massive open foundations, base slabs, cofferdams, massive backfill, emergency repairs, and overtopping protection for  embankment dams. It may be used in lieu of conventionally placed concrete in concrete gravity and arch-gravity dams. RCC may be considered for use in levees where foundations are adequate and may also be used in caps for jetties to reduce the amount of required rock.

 

This 8 PDH online course is applicable to civil, structural or geotechnical engineers, as well as design and construction personnel involved with the planning, design, construction of roller-compacted concrete structures.

This online engineering PDH course provides guidance in hydrologic analysis of interior areas for planning, design investigations, and flood risk reduction.

 

Floods have social, environmental, and economic consequences and they directly impact people and communities. Some of the immediate impacts of flooding includes loss of human life, loss of livestock, and damages to properties and crops.

 

This course provides information of interest to planners and designers of interior system involving flood loss reduction measures and actions. Interior area investigations are differentiated from other studies only by the uniqueness of the hydrologic analysis requirements for the flood loss reduction measures commonly used. Interior area planning studies are an essential aspects of feasibility studies.

 

This 11 PDH online course is applicable to civil, environmental, and stormwater management engineers as well as other technical personnel interested in learning more about hydrologic analysis of interior areas.
