RESTORE ASSIGNMENT: PART I
2015 COURSE ON MASONRY CONSERVATION
DUE: Friday, April 24, 2015
Please answer the following questions using your class lecture notes, the readings in the RESTORE Reader - Selected Readings in Masonry Conservation, and the printed material that has been distributed in class.

1.a) Describe and illustrate the rock cycle. What are the chemical and physical properties of the three basic rock types?

b) List the essential tools needed to create a field test kit to identify rock types. Describe the various physical and chemical tests used to identify rocks (e.g., the acid test, Mohs Hardness Scale, etc.)

2.a) Illustrate and describe the "decay curve" for an un-maintained masonry building

b) What affects the behavior, performance and durability of masonry materials (e.g., properties, environment, construction system, detailing, craft).

3. As a building "pathologist”, discuss the tools and methods you would use for the analysis and identification of conditions on site and also in the laboratory.

4. Describe the role that water plays in the weathering or deterioration processes of masonry materials. In answering this question, focus on:

a) The chemical and physical properties (e.g., mineral content, porosity, permeability or the presence or absence of bedding layers)

b) Crystallization of salts

c) Pollutants

d) Climate - freeze / thaw cycles

e) Thermal cycling

5. Outline and describe the general criteria that should be followed before cleaning a masonry structure.

a) List the types of surface deposits that can be observed on "dirty" masonry.

b) What importance do the chemical and physical properties (mineral content, porosity, permeability, solubility, etc.) of the masonry materials have in determining the cleaning process you select?

c) List the advantages and disadvantages of the following methods for cleaning masonry materials:

1) Spray / Mist Cleaning

2) Pressure Washing and Chemical Cleaning

3) Steam Cleaning

4) Abrasive Cleaning

5) Poultice Cleaning

6. Everyday a host of health and environmental issues / hazards affect the way we work and how we design, specify, use, store and dispose of materials. In order to decode, decipher and understand a Material Safety Data Sheet, what information and / or terminology should the design professional, conservator, craftworker, etc. know (e.g., TLV, PEL, gas, vapor, fume, etc.)?

Please add this to the list, define the terms and explain the importance of understanding this material thoroughly.

Please retain a photocopy of your assignment for your records and submit the original to RESTORE. The original will not be returned to you.

RESTORE ASSIGNMENT: PART II
2015 COURSE ON MASONRY CONSERVATION
DUE: Friday, June 26, 2015
Please Select One: Option A or B

OPTION A

Please submit at an annotated bibliography of at least 20 articles on one of the following topics:

1. Masonry Materials: Properties and Deterioration Mechanisms

2. Technology of Cleaning Masonry Structures

3. Mortar Matching and Repointing

4. Masonry Repair and Replacement Technology

5. Coatings and /or Consolidants for Masonry Materials

6. Health and Environmental Hazards Inherent in Architectural Conservation Materials and Processes

The annotation should include the name of the author, publisher, publication date, name of the publication from which the article was taken and a one or two paragraph summary of the main points of the article. Do not include articles from the bibliography in the RESTORE Notebook Readings on Masonry Conservation.
Please submit two legible copies of five of the articles that you have reviewed.
Please keep a copy for your records of the material that you submit to RESTORE e.g. bibliography and articles. The material you submit to RESTORE will not be returned to you.

OPTION B

An aggregate or sand library is a valuable reference tool for anyone working with masonry structures. A comprehensive collection or library of different aggregates and sands used in masonry formulations will help you to identify and analyze mortars, and to match mortars and composite repair mixes, therefore saving many costly hours of trial and error formulations and installations. A variety of aggregate / sand samples are available from most masonry product suppliers.

For this assignment, collect between 40 and 50 samples of aggregates from a 100 to 200 mile radius around the region in which you work. The sand library should be organized in a display box. The aggregate samples should be placed in small clear plastic containers or clear glass sample bottles. Each sample should be labeled completely and have an index card which provides the following information:

1. A physical description of the aggregate, including

a. Chemical and physical properties,

b. Description of color range of particles

c. Description of particle shapes and sizing

2. Geographic and geological source, if known

3. Supplier’s name, address, phone, fax, e-mail

Please create a duplicate sand library to keep for your own use. The sand library submitted to RESTORE will not be returned to you. If you have any questions regarding this assignment, please call RESTORE at (212) 749-1800.
