To get 1 cuyd of M mortar, you need 27 cubic feet of the components in a 3 to 1 to 12 proportion. It is less workable compared to other mortar types and has less adhesion and sealing properties. Learn more about concrete and cement here in our Buying Guide. The block manufacturing equipment and manufacturing methods have caused the typical strengths to go up considerably. It also has a higher resistance to freeze and thaw. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I don't recall the paper, but, there was some work done about 40 years back on the effects of the mortar joint thickness. All Rights Reserved. Looking for confirmation of my understanding of these issues and recommendation on further references on the topic... Part of the basis is just fabrication quality has gone up and higher strength is more in demand than it used to be. - In the past (when the basic ASTM standards were written), higher cement contents were needed to get the green molded block into the curing areas. The current tolerances are still to loose for good masonry. Know one of the primary masonry suppliers in our biggest market told us that we shouldn't bother specifying 1500 psi anymore. Type M mortar This uses a 3 / 1 / 12 mix and results in a mortar with a 2,500 psi compressive strength. Now, the handing equipment is faster and more gentle and the blocks do not have some of the bulges as older units. Registration on or use of this site constitutes acceptance of our Privacy Policy. This type of mortar is generally used with hard stone. Sorry, you do not have permission to ask a question, You must login to ask question. Miscellaneous - Engineering related topics like Beaufort Wind Scale, CE-marking, drawing standards and more; Related Documents . This cement is designed for very heavy loads and has higher compressive strength than most masonry cements. Type K mortar has the lowest compressive strength. The different areas of construction where the Type M mortar mix is employed are retaining walls, driveways, and foundations. This is a manufactured, premixed, packaged combination of Portland cement, hydrated lime and optional admixtures. Promoting, selling, recruiting, coursework and thesis posting is forbidden. The highest-strength mortar (2,500 psi) is Type M mortar, which is only used where considerable compressive strength is needed. Become VIP Member, Do you need to remove the ads? While this mix is great for supporting heavy loads and below grade foundations, it provides relatively poor bonding and sealing properties. Testing by independent laboratories available upon request (Type S >1800 PSI) (Type M >2500 PSI). It is also used as a mortar mix for soft stone masonry. Related Topics . Easy to mix, just add water. Sand 4. For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f’ m of 1750 psi to 2000 psi for … Use one bag of Coosa Light Masonry Cement with 2 ¼ to 3 cubic feet of damp, loose, masonry sand. Type M. A type M mix has the highest highest amount of Portland which gives it a minimum of 2,500 psi of compressive strength. It is a medium-strength mortar minimum 12.4 MPa (1800 psi) with high bonding ability. I think the f'm of 1500 psi stems from the ASTM C90 absolute minimum block strength of 1900 psi with type M or S mortar (ACI unit strength method). Meets the requirements of ASTM C270 types S, N, or M. *Eng-Tips's functionality depends on members receiving e-mail. Contribute to the serviceability of the masonry. There are different types of mortar with unique purposes. Similarly, if 3,050 psi (21.0 MPa) concrete masonry were used in conjunction with Type N mortar, the maximum f’ m that could be used in design would also be 2,000 psi (13.8 MPa). Recently on projects, some designers are now specifying a higher f’ m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar. - ASTM standards are very slow and cumbersome to be changed. ANSWER: Compressive Strength. The consistency and ease of applying type O mortar mix make it suitable for pointing work and repairing existing structures. Type S mortar has great durability that is why it is highly suitable for locations where the masonry is in contact with the ground, such as paving or shallow retaining walls. Masonry cement is so much easier to use that you don't often find anyone mixing mortar from scratch at a job site anymore although it is a cost effective way to do it. It is used for exterior walls and above-grade walls, which are exposed to severe weather conditions. Since it closely mimics the strength of stone, it will not fail before the stone itself fails. As per ASTM C270, there are mainly five types of mortar that are standardized to meet a variety of masonry applications. My understanding of the explanation for this is that mortar strength has been found through research to not play a major role in the strength of the masonry and that one explanation may be the aspect ratio of the lab mortar cube sample versus the thickness of the mortar is underestimating its strength. The mortar selected for masonry construction must: The type and material of mortar are selected by considering the requirements mentioned above.
