EXPAN 500
EXPAN 500 is an expansive cement additive which, when mixed
in certain proportions with type II Portland cement (ASTM C-150),
results in a type K expandable cement (ASTN C-845), used mainly in
the manufacture of Shrinkage Compensating Concrete (SCC).
EXPAN 500
provides an effective and economical way of preventing cracks
caused by drying shrinkage in concrete made with Portland cement.
- The best option for building industrial floors that require the elimination of shrinkage joints, which are essential in Portland concrete.
- Allows floor slabs of up to 1,500 m² to be built without any shrinkage or expansion joints.
- In storage tanks, it allows micro-cracks, which affect the permeability of the structure, to be reduced as much as possible.
- The only Industrial Flooring Construction System that eliminates construction joints.
- Restricted expansion in the mortar.
- Expansion in 7 days.
- Minimum 0.04%.
- Maximum 0.10%.
- Expansion in 28 days relative to 7-day expansion: 115 %.
- Compressive strength.
- 7 days Min. kg/cm² (psi) - 148 (2100).
- 28 days, min. kg/cm² (psi) - 246 (3500).
ASTM Standard C-845 - "Standard specification for expansive
hydraulic cements".
ASTM Standard C-806 - "Restricted expansion of mortars with
expandable cement".
ASTM Standard C-878 - "Restricted expansion of shrinkage
compensating concrete."
- It is mainly used in the manufacture of shrinkage compensating concrete.
- Applications in the construction of industrial floors without control joints, in storage tanks.
- It can also be used in the production of expandable grouts, mortars and low-shrinkage concrete.
