Low-Density Concrete Properties ...density concrete provides several advantages with the primary, and most obvious, benefit being a 15 to 25 savings in weight without sacrificing the overall strength of a structure. However, the use of low-density concrete can result in a considerable impact to the structural design and cost of the structure. In this course, the student will review Engineer Circular (EC) 1110-2-6054,  more...

Low-Density Concrete Construction Considerations ...density concrete is quite similar to using normal-density concrete. Constructability considerations related to mixing, placing, curing, pumping, and testing controls must be addressed in order to maximize the quality of concrete and avoid problems during construction. The use of low-density concrete provides several advantages with the primary, and most obvious, benefit being a 15 to 25 savings  more...

Introduction to the National Pollutant Discharge Elimination System NPDES Construction Site General Permit ...rbance and compaction of the soil, the loss of vegetation density, and the creation of impervious surfaces. Water quality can be dramatically impacted by inadequate construction site erosion and sediment control measures. For these reasons the Environmental Protection Agency regulates even relatively small construction sites under the Phase II NPDES regulations. Who is regulated? ? Any  more...

Introduction to Conservation Design ...rbance and compaction of the soil, the loss of vegetation density, impacts to natural habitats and the creation of impervious surfaces. All too often ordinance requirements result in a site layout that does not take into consideration the most valuable aspects of a site. Water quality, habitat, and critical ecological features can be lost if sites are fit to a development, rather than fitting a  more...

Hydraulic Design of Energy Dissipators for Culverts and Channels Overview The discharge from culverts can cause erosion and subsequent sedimentation problems if not controlled at the source. To mitigate this problem the discharge energy can be dissipated at the source. This course will provide design information for energy dissipation problems at culverts. Several energy dissipators will be discussed including USBR Type III and IV stilling basins, SAF  more...

Introduction to Cathodic Protection of Underground Structures Overview This is an introduction to cathodic protection for underground structures such as tanks and pipelines. It covers the two principal methods used to mitigate corrosion: the sacrificial anode and impressed current systems. It introduces you to the nine steps in designing a sacrificial anode system, the thirteen steps in designing an impressed current system, and the field testing  more...
