  • the present invention relates to a mortar composition used in construction industry. Particularly, the present invention relates to a polymer mortar composition applicable for EIFS construction under lower temperature. Introduction
  • Exterior Insulation Finish System is an exterior wall cladding system, and is also known as External Thermal Insulation Systems (ETICS) in Europe. It can be used on both residential and commercial buildings for the purpose of saving energy, improving room comfort and protecting walls against moisture and other external elements.
  • polymer modified mortars are normally prepared to form an adhesive layer used for adhering a thermal insulation board onto a substrate, such as a wall, and a basecoat layer used for leveling the surface to which a finish layer would be applied and reinforcing the flexibility of the system. Both layers are applied on the thermal insulation board as a thin mortar layer, normally with a thickness less than 10 millimeter (mm). Cement strength develops best at a temperature above 5°C, so application of mortars in EIFS structures must be conducted at temperatures above 5°C. In North China, no EIFS can be installed for three months in a year due to the cold winter.
  • Some cementitious mortars (“low temperature non-EIFS mortars”) are useful for non-EIFS construction under lower temperature.
  • sulfate aluminate cement has been used to replace Portland cement in cementitious mortar ⁇ see, for example, "Advantage of sulfate aluminate cement in winter construction", Engineering Construction and
  • Sulfate aluminate cement has more calcium aluminate than Portland cement and hydrates faster, generating more heat than Portland cement. Hydrated sulfate aluminate cement has a higher early strength at lower temperatures, even below zero degrees Celsius (°C). It is also known to introduce salts such as chloride and nitrite to lower the freezing temperature of water added to a polymer mortar so that the cement can hydrate and the polymer used in a polymer mortar can form a film at a temperature below 0°C (see, for example, US6126850A and SU617417A1). It is further known to introduce an "early strength agent (coagulation accelerator)", such as calcium formate, Li 2 C0 3 and superplasticizer to increase early strength of cement (see, for example, CN101591160A and CN101993229A).

  • these low temperature non-EIFS mortars are not EIFS-applicable. There are different technical requirements between EIFS applicable mortars and other applications. As a result, these low temperature non-EIFS mortars leave unsolved problems when used to prepare the two thin mortar layers in EIFS.
  • the known mortars are not sufficiently flexible for EIFS applications. When using them for preparing the thin mortar layers in EIFS they tend to result in cracks in the mortar layers upon curing of the mortars. Additionally, the known mortars cannot meet the requirements of the bonding strength necessary for the mortar layers attached with a thermal insulation board in EIFS.

  • Aluminate cement also named high aluminate cement, is a kind of water-hardening material with faster early strength enhancing rate. It is made by fusing a mixture of bauxite and limestone or by sintering. Aluminate cement has different mineral components compared with Portland cement (silicate cement) and sulfate aluminate cement.
  • Aluminate cement normally comprises CA(CaO Al 2 0 3 ) as its main component, while 3CaO Si0 2 , 2CaO Si0 2 , and C 3 A (3CaO Al 2 0 3 ) in Portland cement and C 4 A 3 S D (3Ca0 3Al 2 0 3 CaS0 4 ) in sulfate alumina cement.

  • Gypsum is powder of calcium sulfate crystal and a very soft mineral mainly composed of hydrated calcium sulfate with the chemical formula CaSCvnl ⁇ O, for example dihydrated gypsum, anhydrate gypsum and semi-hydrated gypsum.
  • Calcium sulfate is used to control the setting time of cementitious materials. It can react with C 3 A (tricalcium aluminate) and Ca(OH) 2 in Portland cement to produce ettringite (AFT). See chemical equation (a). AFT adheres and covers the surface of C 3 A which has the fastest hydrated speed in Portland cement. As a result, AFT can prevent further hydration of C 3 A and will eventually prolong the setting time of the cement, which increases the working time of the formulated mortar.

AFT will fill into the structure of the cementitious system and make the structure dense. In addition, when gypsum is insufficient in the composition, calcium sulfate will react with C 3 A to produce AFm. See chemical equation (b). AFm can expand and thus compensate the shrinkage caused by C 3 A hydration.
