The main components of this additive are synthetic polymers that can significantly reduce the mixing water and significantly increase the strength of concrete, especially in its early ages. MTOCRETE N-660 concrete lubricant does not contain chlorine. An additive based on synthetic polymer with the ability to significantly reduce concrete water and significantly increase concrete strength at early ages.
A high range reducing superplasticising
Of rheoplastic concrete
Based on ASTM C-494 T A,F
Production of strong concrete
Precast concrete
Concrete with a low water-cement ratio
In complex forms and with reinforcement density
MTOCRETE N-660 concrete lubricant provides a place to produce flowable concrete with very little water to cement production. Table No. 1 shows examples of concrete with a low water-cement ratio. MTOCRETE N-660 lubricating concrete has higher resistance compared to concrete without additives and with the same efficiency. The apparent increase in resistance remains at later ages. The initial and final setting is not much different compared to the concrete additive. Therefore, if there is a need for more transportation time or additional work, it is recommended to use a super lubricant with retarding properties, such as MTOCRETE N-660 concrete lubricant.
Due to the decrease in the ratio of water to cement, other properties of hardened concrete are also improved. such as less permeability, less shrinkage and creep and increased modulus of elasticity.
MTOCRETE N-660 concrete lubricant is compatible with all standard cements. MTOCRETE N-660 concrete lubricant along with concrete foaming additive MTOAIR 220 foaming additive is recommended in places where stability against melting and freezing cycles is required.
MTOCRETE N-660 concrete lubricant packaging:
MTOCRETE N-660 concrete lubricant is available in 25 kg gallons, 220 kg barrels and large tanks.
Appearance: brown fluid
Specific weight: 1.185 to 1.195 grams per cubic centimeter
Entrained air: 1% maximum
Chlorine content: chlorine-free, based on English standard 5075
Nitrate content: No nitrite
mtocrete N-660 concrete lubricant is normally used between 0.8 and 1.2 liters per 100 kg of cement.
Other values may be used according to the working conditions and the type of materials used.
Effects of additional use of MTOCRETE N-660 concrete lubricant
Too much consumption of MTOCRETE N-660 concrete lubricant leads to the following results:
1. Delay in setting of concrete
2. Slight increase in the amount of air bubbles
3. More efficiency
MTOCRETE N-660 concrete lubricant must be added to the concrete mix along with the adjusting water. More mixing time is not required. Never mix mtocrete N-660 concrete lubricant with dry cement. In ready-made concrete, an additive can be added to the concrete through the back valve of the mixer and mixed for about 3 minutes at a speed of 10 rpm to obtain a uniform mixture. If the purpose of using MTOCRETE N-660 concrete lubricant is to obtain high initial strengths, the amount of water should be reduced to a large amount.
mtocrete N-660 lubricant is added along with the mixing water. The better lubrication effect or the water reduction property is greater when 50 to 70% of water is added to the mixture after mixing. It is not recommended to add this material to cement or dry materials.
If it is kept in a covered place and away from direct sunlight and high heat, the useful life of this mare will be one year. Failure to observe the proper storage method will damage the product or its container.
Protection and safety of concrete lubricant MTOCRETE N-660
MTOCRETE N-660 concrete lubricant does not contain any dangerous substances.
Making the market is a database and a network of manufacturers and suppliers of construction products that introduces companies and specialized reviews of construction products. The general purpose of building a market is to establish a direct relationship between the buyer and the producer. Dear buyers, to know the price of concrete lubricants, refer to the market system and buy MTOCRETE N-660 concrete lubricant from reliable sellers.
Manufacturers and suppliers can register in the market construction system and participate in the special sales festival by placing construction products and inserting the suggested price and increase the sale of their products.
