Abstract:
A program for the evaluation of discharge in line-drainage systems was developed. Complex hydraulic situations are treated, such as lateral inflow varying along the drainage channel with respect to the shape of the drainage area. Sudden changes in the cross sections and flow hindering structures are to be treated. Additionally, sand may be accumulated in the channels and the maximum possible accumulation can be known for a given runoff. The programs were checked against hydraulic investigations.

SP-116 Polymers in Concrete: Advances and Applications gathers and evaluates the latest information on the effects of polymers in concrete. This important ACI publication, a collection of 12 symposium papers combining the development of new concrete polymer materials, give greater insight into the advances of polymer concrete. Gathering expertise form around the world, Polymers in Concrete: Advances and Applications presents case studies such as cold weather polymer concrete repair; performance of multiple layer polymer concrete overlays on bridge decks; electrically conductive polymer concrete facing; influence of aggregate on the fracture properties of polyester polymer concrete; and future trends in polymer concrete. The mission of ACI Committee 548 is to gather and evaluate information on the effects of polymers in concrete. It has sponsored six symposia, all of which have received world-wide acclaim.

Styrene-butadiene latex modified concrete system is an effective technique for repair and rehabilitation of parking garage decks. The system appears to retard corrosion of the reinforcing steel and has many benefits, including ease of placement and workability, superior flexural and bonding strength, and deicer scaling resistance. Styrene-butadiene latex modified concrete can be applied in parking structures during the winter months with few problems.

Fracture behavior of polyester polymer concrete was investigated at room temperature using single edge notched beams loaded in four-point bending. To investigate the effect of particle size distribution on the fracture properties, polyester polymer concrete systems were formulated using both uniform Ottawa 20-30 sand and well graded blasting sand. The notch sensitivity of polyester polymer concrete systems was investigated by varying the notch-to-depth ratio up to 0.7. The results are analyzed to examine the applicability of fracture parameters such as critical stress intensity factor KIC and critical J-integral JIC, to characterize the fracture behavior of polyester polymer concrete. This concrete is a notch sensitive material, and if it contains well-graded aggregate, it has better fracture properties than the uniformly graded aggregate system.

Composite materials based on sulfur polymer cement (SPC) and mineral aggregate have been developed by the U.S. Bureau of Mines as part of a program to utilize abundant mineral resources. Program goals are to develop durable, chemically resistant construction materials to increase productivity in the chemical, fertilizer, and metallurgical industries by lowering maintenance costs for labor, energy, equipment, and material. This paper describes the research related to development of SPC, the sulfur concrete (SC), and the industrial testing, together with commercial-scale equipment development and large-scale construction practices. Thermoplastic SPC is produced commercially by reacting cyclic olefinic hydrocarbon chemical modifiers with elemental sulfur at 300 F (149 C) in a sealed chemical reactor. The molten SPC is mixed with mineral aggregates, producing a high-strength concrete product with an average compressive strength of 7000 psi (48 MPa) upon cooling. State-of-the-art production and construction techniques are described. Currently, SC materials are showing superior performance characteristics to portland cement concrete (PCC) in special industrial applications where corrosive environments exist.
