What is Mortar?

Rapid Setting Mortar Significance Move at quicker rate Less time on the job Reduced job cost

Colloidal Silica * Nano-silica particles that have been pre-suspended in liquid * Effects on mortar: improve flowability, decrease set-time, and increase compressive strength.

Objective- Test effects of Colloidal Silica Design mortar mix. Create different samples. Test each mix. Compare results.

Timeline Time Activity Assigned Person February Research, gather materials, and prepare lab equipment. Blake/Jordan   Lab 1- Mix control sample, sample 1, and sample 2- Test setting time and flowability. Compression test of control sample, sample 1, and sample 2 (1 day aged). Jordan March Complete compression test (7 day and 28 days aged) of control, sample 1, and sample 2. Results and Analysis- 1st lab. Lab 2- Mix sample 3- Test setting time and flowability.  Blake April Complete compression test of sample 2 (1 day, 7 day, and 28 days aged). Results and Analysis- 2nd lab. Blake May Compare results of the 3 samples to the control sample. Prepare for final presentation.
