Concrete Protection Slab
Concrete protection slabs are a very common method of protecting a pipe or service from damage or overloading from imposed loads. Concrete protection slabs are often installed to drainage pipes, gas and oil pipelines, electrical service ducts and any other type of underground utilities or services.
Pipeline Protection Slab Design
Pipeline protection slabs are standard design details which are used to protect pipelines and other underground services from imposed loads on the surface. They are usually required when there is a requirement to install the pipeline at a shallow depth, though sometimes concrete protection slabs are used to protect deeper pipelines from heavy imposed surface loads.

FAQ – Spancrete SMA
For roof slabs, a span-depth ratio limit of 50 is suggested. In practice, a span-depth ratio of 45 is common for floors and roofs where fire endurance, openings, or heavy or sustained live loads do not control a design. Example: 10″ Spancrete® roof with a span to depth ratio of 50. 10″ x 50 = 500 /N.

Continuous steel-reinforced concrete slabs are vulnerable to corrosion damage and cracking. Non-metallic basalt fiber-reinforced polymer (BFRP) bars have a great potential to overcome corrosion problems. In this paper, test results of six continuous concrete slabs internally-reinforced with BFRP bars are reported. The specimens were divided into two groups based on the BFRP reinforcement ratio ...
