WATER & MOISTURE RELATED ISSUES IN

CONCRETE SUBSTRATES

POROSITY OF CONCRETEAllows Moisture To Travel Freely Inside ConcreteIncreases Absorption Of Contaminating Materials

MOISTURE CAUSES CONCRETE DETERIORATION & FAILURE

Increases The Absorption Of Chlorides From De-Icing MaterialsDissolves & Activates Free Alkali Materials That Attack The Concrete

WATER & MOISTURE RELATED ISSUES IN

CONCRETE SUBSTRATES

SILANE & SILOXANE TREATMENTSMoisture intolerant at application time.Achievable dosage drastically reduced in the prescience of small

internal moisture contentLittle resistance to chloride penetration after application on damp

substrate.

CRYSTALLISATION TREATMENTMoisture tolerant at application time.Accepts and works with moisture in the concrete substrate.Uses substrate moisture to form protective crystalsResistant to chloride penetration not disadvantaged by concrete

moisture.

STANDARD “VS” CRYSTAL TECHNOLOGY WHEN MOISTURE IS

PRESENT

SECTION 1 (CORE 1) SECTION 2 (CORE 2) SECTION 3 (CORE 3) SECTION 4 (UNTREATED REFERENCE

*Procedure: (i) cores repaired with Silicon to reduce lateral seepage of dye solution, (ii) cores inverted in dye solution for 4 days, (III) cores removed from dye solution and allowed to air dry for 48 hours, (iv) buttons cut from cores, (v) sections wet cut from core buttons, (vi) sections dried and photographed. Slight smudging of the dye can occur as a result of the wet cutting process.This is a small effect compared with overall dye penetration. Isolated occurrences of natural fluorescence are rare and distinguishable from the dye used. Sections Nos. 1, 2 & 3 indicate that THE CRYSTALS has provided substantial resistance to water ingress. For reference purposes, section 4 shows typical absorption in a comparable untreated concrete.

ASTM C666 & ASTM C1262-98 Rapid Freeze Thaw

UK ASTM C1262-98: Substantial reduction in mass loss and rate of mass loss in manufactured concrete railway posts.

Negligible length change, mass loss and reduction of dynamic modulus

Freeze-thaw is an extremely important issue in many UK regions.
