    Add 10kg RDP or 20kg RDP into 1mt tile adhesive, Feeling no difference?

    10KG RDP and 20KG RDP difference is in the pullout force, PVA can improve the initial adhesion, it has a certain viscosity, such as your 10 kg RDP can be replaced with 2 kg PVA with 8 kg RDP, 20 kg RDP content is no need to add PVA.

    How about this self-leveling mortar formula?

    This recipe is not bad The proportion of cementitious material can be adjusted, the amount of Ordinary Portland Cement less, add more high-aluminum cement, if 60 kg of high-alumina cement, 24-hour strength and polished estimated more difficult. Gypsum is too small, I usually use 40 to 50 kg...

    waterproof putty formulations

    Specifications of HPMC seems to be good but better if DS is specified. What we need is good workability and water retention on 0.3-0.4% use with 10%Cement and 85-90% inert on less than 250 mesh size. How much RDP is needed to achieve min 1.2 N/mm2 strength on 2 days and 7 days. Specifications...

    Why should thin-layer masonry mortar be developed?

    The thickness of masonry mortar joint is generally 8-12mm, mainly determined by the dimensional accuracy of the block material. The lower the dimensional accuracy of the block material is, the thicker the mortar joints will be required. In general, the strength of mortar joint is lower than that...
