    Characteristics of hydroxypropyl methylcellulose (HPMC) in construction materials

    WorkabilityThe workability of the plaster is significantly improved by the addition of HPMC. Mortar without the addition of HPMC was loose and prone to water loss. With the addition of HPMC, however, it seems to have an "oily" quality, giving the wall a full joint and a smooth surface. It makes the

    Why mortar should have hydroxypropyl methylcellulose added?(1)

    Hydroxypropyl methylcellulose has an important role in mortars, and that is water retention. Mortars with poor water retention are prone to segregation and water loss during transport. When laid on the surface of porous materials, most of the water is easily absorbed and the properties of the mortar
