General DetailsMovement of joints in concrete structures is caused by:

The factors that cause joints to open are the most significantwhen optimising joint design for sealants.Because joints move, sealants must be elastic and flexibleto avoid splitting, tearing and loss of adhesion.A sealant’s flexibility is defined by its strain capacity,expressed as a percentage change in nominal joint width.

Joint ConfigurationThe shape of the sealant within a joint influences its abilityto stretch with movement.Correct Width to Depth Ratio

Incorrect Joint Configuration

Joint DesignFollowing is a simple, conservative method for calculating minimum joint width. For more accurate and rigorous treatment,consult the references listed below.

Minimum Joint Width, Lmin = 100 / Sealant Strain Capacity x L…(1L = Anticipated joint movementL = Lt + Lcs………………………….(2

Lt = Change in Joint Width due to Temperature Change (mm)Lcs = Change in Joint Width due to Concrete Shrinkage (mm)

Lt = L x c.temp x T…………………….(3L = Joint Spacing (mm)

c.temp = Coefficient of Concrete Thermal Expansion (mm/mm°C)T = Change in Temperature (°C)

Lcs = L x cs……………………………..(4L = Joint Spacing (mm)

cs = Concrete Shrinkage Strain = 850 x 10-6 mm (Conservative. Refer AS3600 Clause 6.1.7 for accurate values)In this simple method, effects that cause joints to close are ignored, as they do not impart tensile strain on the sealant. Forexample concrete creep and temperature increase cause joints to close resulting in compression of the sealant.

Worked Example:Concrete Panel Width = L = 4m, Thickness = 150mm, Installation Temperature = 30°C, Minimum Temperature = 5°C.Sealant = Ramset™ HiSeal™, Strain Capacity = ± 25%, c.temp.temp = 12 x 10-6 mm/mm°C, cs = 850 x 10-6 mm

Lt = 4 x 1000 x 12 x 10-6 x (30 – 5°C) = 1.2 mmLcs = 4 x 1000 x 850 x 10-6 = 3.4 mm

Lmin = 100 / 25 x (1.2 + 3.4) = 18.4 mm

Installing Ferrules into Solid Concrete with Ramset Epoxy GroutTo create a post installed internally threaded fixing, Ramset have developed a method of installing ferrules into solid concrete with Epoxy Grout instead of the

traditional cast in method.

For more information on Ferrules contact your local Ramset Engineer.

Working Load Limits in Tension of Ferrules installed in Solid Concrete with Ramset Epoxy Grout

are limited by concrete cone capacity. Check tensile capacity of bolts to determine if fixing load capacity is limited by steel

37.3 CURINGPrevent moisture loss of hardened grout by applying water to the surface or covering exposed grout with wet Hessian, plastic sheeting or Ramset Concrebond or other curing compound. Keep grout thoroughly moist for a minimum of 48 hours to prevent drying shrinkage and cracking. If required remove formwork after 24 hours and protect exposed grout from moisture loss as described above.High wind conditions will affect the drying surface of grout; take precautions to protect the material from prevailing weather.
