Chemical Admixtures Used in Digital Manufacturing (3D Printing) of Building Materials
Digital manufacturing (3D printing) has successfully made its first entry into the construction industry. Apart from the hardware, chemical admixtures play a most critical role in allowing successful printing of cementitious products. At the moment, mortars of high cement content are commonly used as ink which is well conditioned by the addition of chemical admixtures. PCE superplasticizers are applied to achieve pumpability while CAC suspensions provide structuration and shape stability for the extruded mortar. Sagging is prevented by thixotropic agents including nano clays which induce gellation, and adhesion between individual printed layers derives from film-forming latex polymers. Moreover, C-S-H-PCE nanocomposites can sufficiently boost early strength development to allow the printing of larger structures. Still unresolved is the significant autogeneous and dry shrinkage experienced in 3D printed objects as commonly applied shrinkage reducing and shrinkage compensating technologies are insufficient. Major new technologies will need to be developed to allow the digital manufacturing of larger concrete objects containing steel reinforcement, and chemical admixtures will play a pivotal role to achieve widespread success of this technology in the future.

Dr. Jean-Yves Petit | Organik Kimya Netherlands B.V. | Rotterdam, The Netherlands:
Design Parameters of Re-dispersible Polymer Powders Affecting Flow Ability of Self-levelling Compounds
Self levelling underlayments / compounds are fine mortars with self levelling properties, usually formulated with different polymers to enhance their rheological, physical and mechanical properties. Among the polymers used, the latex redispersible powders are used as secondary binder to increase abrasion resistance and flexural strength, but they should also improve flowability of the mortar at fresh state and not be detrimental to shrinkage reduction. Therefore, the design of this class of specialty products should be taking into consideration the complexity of phenomena happening in the final mortar. The effect of the polymer design on flow ability of self levelling compound was investigated. Results show that the polyvinyl alcohol used for polymerization, the anticaking system, the protective monomer and the amount and mobility of the polymer in the cement matrix are key parameters to design a specialty powder polymer for self-levelers. Low molecular weight polyvinyl alcohol allows getting a shear-thinning index as close as possible to avoid any dynamic segregation during the pumping phases of the mortar. Acrylic monomers as protective monomers enable to have a free defoaming effect which enhances flow properties, such as the use of round shaped pozzolans in the anti-caking system.

2. 5th MORTAR CONVENTION, 27. to 29 April 2021: Program

Delegate registration has started for the  5th MORTAR CONVENTION, which will take place as Live Event Online from 27. to 29. April 2021. Our new, extended concept gives delegates, scientific institutions and supporting companies many more communication options, in ample of spare time delegates can meet with friends or re-view lectures they missed the other day. Our sponsors can offer exclusive workshops (webinars) or actively create person-to-person meetings by video chat with their customers (sponsors: please choose your additional options and book your client invitation packages). There will also be a drymix.info lounge to have a virtual drink with us and smoke imaginary cigars...

3. Cersaie both Real in Bologna - and Virtual for 3 Weeks in September/October 2021

The organizers of 38th Cersaie - The International Exhibition of Ceramic Tile and Bathroom Furnishings - Cofindustria Ceramica and Edi.Cer., both Sassuolo, Italy, and Bolognafiere have announced that this year's Cersaie will take place as a real five-day event as well as virtually (for a longer period of time). This way, the organizers hope to create viewing opportunities for international buyers that can not yet come to Italy, while at the same time offering the classic industry fair atmosphere in Bologna. The real Cersaie takes place from 27. September to 1. October 2021, with over 80% of industry participation when compared with 2019. The show will be accompanied by Cersaie Digital, which will be online for three weeks from 20. September to 8. October 2021.

4. RLA Polymers Acquires Australian Waterproofing Expert Gripset

RLA Polymers Pty. Ltd., headquartered in Melbourne, Victoria, Australia has announced it will acquire the Gripset business, Kilsyth, Southern Australia. Founded in the seventies of the last century by Sam Scardigno as a specialty contractor, the company soon became an expert on waterproofing and has developed this portfolio further up until today. RLA Polymers announced it will operate Gripset as a separate business unit within RLA. A transaction value was not disclosed by either party. In 2020, Gripset had a turnover of about 15 mio Euro. According to RLA’s Managing Director Troy Hogan, Gripset's Sales, Technical, Customer Service, Marketing, Senior Management (including owner/founder Phil Scardigno) will be part of RLA's Gripset division. “I believe the Gripset brand is a great fit for RLA’s continued expansion, enabling our waterproofing technologies to gain a broader reach across the national construction industry”, Phil said.
 

5. Wacker Polymers Announces Global Price Increase for Dispersions, Resins and Redispersible Powders

Wacker Polymers, a Division of Wacker Chemie AG, Munich, Germany is increasing its prices for dispersions, resins and redispersible powders globally. A price increase of 10% comes into effect on 15. March 2021 for the entire product range or as customer contracts allow. According to Wacker, this step became necessary due to increased raw material cost, which in part has been caused by tightness in supply of particular raw materials in the global markets.

7. Bostik Germany Expands with Drymix Mortars

Bostik GmbH, Borgholzhausen, Germany, has recently acquired 5.000 sq.m. of land adjacent to its main manufacturing location in Borgholzhausen. Bostik plans to build its new drymix mortar plant there, which will double the capacity for the production of self-leveling flooring compounds (underlayments), cementitious tile adhesives (CTA) and grouts. Bostik also plans to re-structure its entire areas in Borgholzhausen by relocating the logistics center into a new location in May of this year. This way yet another 15.000 sq.m. of former warehouse space can be gained for R&D, customer service, sales and training and eduction facilities. Production of adhesives for parquet and carpets as well as industrial adhesives will also be streamlined and partially be relocated.
