Mr. M (hereafter "M"), a development engineer at a construction materials manufacturer, is asked by a client for a repair mortar that can be used in environments prone to deterioration and is suitable for a wide range of construction methods.

* This is a hypothetical example posted as a reference for those with similar challenges

Key Challenges

  • Applying repair mortar using various construction methods suited to the site.

  • Developing a mortar that can be easily mixed on-site with high substrate adhesion and bonding properties.

Mortar is a material primarily composed of cement as a binding agent, sand as fine aggregate, and water to hydrate and harden the cement. By adding various admixtures, the bonding strength between cement particles can be significantly increased, allowing for adjustments in properties such as adhesion, durability, and workability according to the intended use.

M considers innovating a mixing agent to respond to client requests. The mixing agent for repair mortar is required to ensure adhesion to existing structures, as well as to suppress drying shrinkage and improve water resistance and durability, in order to prevent re-deterioration after repairs.

It is important that the material mixes well with cement, forming a uniform and stable hardened structure that can coexist with the hydration reaction of cement, without causing separation or rapid thickening during the mixing process. Furthermore, to meet the needs of clients who want to easily mix materials on-site, the ease of mixing with cement is also a key point.

M finds the additives "ACRYSET CE-515" and "ACRYSET CE-564" on a web page, so he contacts the manufacturer, Nippon Shokubai.

Emulsion suitable for mortar mixing applications for problem-solving.

  • ACRYSET™ CE-515 (Strength-Focused Type)

  • ACRYSET™ CE-564 (Type emphasizing elasticity and followability)

Solution Summary

  • The acrylic emulsion "ACRYSET™ CE Series" that can be utilized for mortar mixing has good compatibility with cement and can provide excellent adhesion to various substrates for residential and road repair applications.

  • The formulation of ACRYSET™ CE-515 is expected to impart freeze-thaw resistance and salt resistance.

When M speaks with the sales representative about the details of the acrylic emulsion "ACRYSET CE series", he learns that CE-515 is a strength-oriented type, and it is expected to improve adhesion to various substrates. They also mention that CE-564, which focuses on elasticity and compliance, can be introduced.

He hears that it might be possible to use it for various purposes such as residential and road repairs, as well as for cross-section restoration. He promptly decides to obtain samples of the ACRYSET CE series and start the evaluation.
