PDF 506R-16: Guide to Shotcrete - American Concrete Institute

gate in both processes, the rotary gun for dry-mix shotcrete, and more efficient concrete pumps for wet-mix shotcrete were introduced. Many improvements were made to wet-mix equipment, primarily concrete pumps and materials, in the 1970s and 1980s. These improvements allowed pumping low-slump shotcrete mixtures longer distances at greater volumes.

Concrete, Block and Brick Diamond Core Drilling Dry vs Wet

Block, brick, or soft concrete are still the only recommended materials to use a dry core bit to drill. Horizontal drilling is preferable to vertical when drilling dry because the dust is not extracted efficiently leading to slower drilling and more binding of the bit. A dust "muzzle" can be used with a vacuum to contain the slurry from wet

What Are Gunite and Shotcrete? - The Balance Small Business

Sprayed concrete can use the same steel reinforcement as poured concrete or precast concrete. Typical shrinkage ranges from 0.06 to 0.10 percent after 28 days of drying. This is typically slightly higher than poured concrete of similar strength. Sprayed concrete must be protected from rain until it obtains its final set, usually four or five hours.

How to Dry Concrete Prior to a Coating Application

Moisture in the concrete. Today, most coating manufacturers require concrete substrates to be dry (<5% moisture content) with low vapor transmission (< 3-5lbs per 1000 sq. ft./24 hours) before applying most types of membranes. This applies to both new and existing concrete substrates, although each may have its own set of moisture-related problems.

Curing Concrete - How Long it Takes & How To Cure - The

When waiting for concrete to dry, keep these timeframes in mind: 24 to 48 hours - after inital set, forms can be removed and people can walk on the surface. 7 days - after partial curing, traffic from vehicles and equipment is okay. 28 days - at this point, the concrete should be fully cured.

Sprayed concrete

There are essentially two methods of application: the dry process and the wet process, typically installed by different specialist contractors and equipment. Both use high velocity air to propel. Dry process sprayed concrete: a predetermined dry mix of cement and aggregate is propelled through a spraying nozzle, where a finely atomised spray of
