Find Labs Significance and Use 5. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results. Therefore, it is recommended that the specific test instrument and loading fixture be mutually agreed upon between the interested parties. Test Method C is suitable for that determination.
University of Pennsylvania, Philadelphia, PA. Abstract This thesis focuses on the evaluation of the durability of potassium silicate coating on concrete surfaces, in particular the exterior concrete walls at Jackson Lake Lodge located in Grand Teton National Park, Wyoming.
The main building on the site, the Central Lodge, is a large 61 year old structure that is in need of a new architectural coating to prolong its service. This structure, once dubbed the ugliest building in America, is now cherished and appreciated for its significance in ushering in a new era of Modernist-style buildings constructed within National Parks.
Because the pH of the concrete walls has fallen to 7, the original architectural coating—acid stains—is not a viable option to recoat the structure.
New coatings must be explored such as mineral silicates. Comprised of a waterglass solution and inorganic pigments, mineral silicate coatings impart a durable colored finish to cementitious and silica-rich substrates.
Developed in Europe, mineral silicate paints and stains have been around for over years. Recently this coating system has gained traction in the United States for its durability and performance enhancing properties. This testing program used a variety of analytical methods such as accelerated weathering, spectrophotometry, water vapor transmission rate tests, water immersion tests, RILEM tube tests, contact angle measurements, and pH readings to evaluate the color durability, water vapor permeability, and liquid water repellency characteristics of potassium mineral silicate coatings.
This evaluation was conducted to determine if potassium silicate coatings can be viable alternative architectural finish to restore the original appearance of the Central Lodge, while improving the performance of the concrete.The performance of a concrete is significantly influenced by its mixture proportion and the coating thickness on aggregate surface.
The concrete in this study is designed by estimating the blending ratio of aggregate using a densified mixture design algorithm (DMDA) based on an ideal grading curve and estimating the paste volume as the sum of the amount of paste needed to provide an assigned.

Evaluate bond strength of coatings and cementitious material with pull-of testing The quality of concrete repairs is determined by the adhesive strength between the repair material and the substrate.
Pull-off testing is the most widely used test method to assess bond strength. Durability of Silane Sealer in a Highly Alkaline Environment Cameron David Murray University of Arkansas, Fayetteville Durability of Silane Sealer in a Highly Alkaline Environment A thesis submitted in partial fulfillment hot, pressurized water.
The purpose of this research is to evaluate the effectiveness of silane when used in this. The main challenge of the self healing concrete project is to ensure the healing agent can survive the mixing process. In order to do that the researchers had to coat the healing agent particles which is an expensive process.
How to Repair Cracks and Resurface a Concrete Driveway Most driveways and patios develop a crack or two in the concrete over the years. These can be caused by everything from tree roots and movement of the soil to freezing and thawing cycles in the winter.
