CHEMICAL AGENTS Chemical agents can be used for presplitting concrete. For this to be used, the depth of boreholes should be ten times the diameter of boreholes, or more. This method is expensive. However, it works very well when presplitting vertical planes of significant depth. In the early hours of use, chemical agents can blow out boreholes and cause personal injury. It is not uncommon for rotary-head milling or mechanicalimpacting methods to be used in conjunction with chemical presplitting methods to obtain a completed job.

The big risk is stability against overturning or sliding. A failure via subsidence is generally related to a faulty foundation. Long-term consolidations, new loading conditions, and related faults are contributors to subsidence. Geotechnical investigations are often needed when subsidence is evident. Things to look for when structure movement is suspected include cracking, spalling, misaligned members, and water leakage. Specialists are normally needed for these types of investigations. Spiral reinforcement for cast-in-place concrete must not be less than 3⁄8 inch in diameter.

Unless otherwise authorized, it is a code violation to weld crossing bars that will reinforce concrete. Techniques for stopping, or controlling, corrosion include the use of concrete with low permeability. In addition, good workmanship is needed. Here are some tips to follow: ■ ■ ■ Use as low a concrete slump as practical. Cure the concrete properly. Provide adequate concrete cover over reinforcing material. Corrosion 25 ■ ■ ■ Provide suitable drainage. Limit chlorides in the concrete mixture. Pay special attention to any protrusions, such as bolts and anchors.
