Mixing Cement Type Citadel Masonry Cements
Next, add the masonry cement and the rest of the sand. No admixtures should be used without written approval. Colored mortar should not be retempered. At their simplest, masonry cements are a mixture of portland or blended cement and a plasticizing material, such as hydrated lime, which retains water and lends “workability” to the mortar mix – a measure of ease of use for masons.
Other applications include stucco and cement-based plasters. Premixed masonry cements offer consistent and uniform performance. N is for general use in most mortar and stucco applications. Refer to paint manufacturer directions for application instructions. Can also be used for scratch and brown coat in stucco applications. Mixing should continue for at least three minutes. Mortar is the glue that bonds masonry units like brick, block and stone together to form a single mass. Can also be used for scratch, brown and finish of walls. This type is ideal for anything that is exposed to severe weather and high heat. N is made of 1 part portland cement, 1 part lime and 6 parts sand.

Mixing should continue for at least three minutes; extending mixing up to five minutes improves mortar qualities. Wear tight-fitting goggles, protective respiratory masks, gloves and protective clothing. Rinse tools before material hardens. Build walls, planters, and chimneys. Masonry cement is mixed with sand and water to produce mortar for brick, block and stone construction. Air-entraining agents protect mortar from freeze-thaw damage and provide additional workability. If breathed in, move person to fresh air. Materials, construction methods and environmental conditions at the time of construction as well as curing play an instrumental role in the final color and appearance of the finished mortar.
Product availability may vary by region. S mortars are required to have a minimum of 1800 psi and their mixes usually give you strengths ranging between 2300 and 3000 psi.
Static discharge may result in damage to equipment and injury to workers. If exposed or concerned, get medical advice or attention. Immediately wash gently and thoroughly with lukewarm, gently flowing water and mild soap for 15-20 minutes. If skin irritation occurs, get medical advice or attention. Water jet may cause spattering of the corrosive solution. Corrosive; reacts with water releasing heat and forming an alkaline solution. Allow material to dry or solidify before disposal.
Mixing Mortar For Masonry
Promptly remove dusty clothing or clothing which is wet with cement fluids and launder before reuse. Heavyweight nitrile gloves, boots and body-covering clothing may be used to prevent dermal exposures to this material and for cleaning and maintenance operations. Consult with respirator manufacturer to determine respirator selection, use and limitations. Some ultra-sensitive individuals may exhibit an allergic response upon exposure to cement products, possibly due to trace amounts of chromium (hexavalent chromium salts).
Inflammation of the respiratory passages, ulceration and perforation of the nasal septum and pneumonia has been attributed to the inhalation of dust containing calcium oxide.
Long-term exposure to fine airborne crystalline silica dust may cause silicosis a form of pulmonary fibrosis that can cause shortness of breath, cough and reduced lung function.
If materials other than those used to establish conformance are to be used in the work, reestablishing conformance to the property specification is required.
