HEMC LH 620M

EipponCell® HEMC LH 620M hydroxyethyl methyl cellulose is an effective additive for mortar formulation, offering unique benefits to enhance its properties.   When incorporated into mortar, it leads to the creation of a more porous and pliable mixture.

During testing, when the mortar test block is folded, the presence of pores contributes to a reduction in flexural strength.   However, the inclusion of the flexible polymer within the mix counteracts this effect by increasing the mortar’s flexural strength.

Consequently, the combined influence of these factors results in a slight overall decrease in the flexural strength of the mortar.

Under pressure, the composite matrix is weakened due to the limited support provided by the pores and flexible polymers, leading to a reduction in the mortar’s compressive resistance.   This is particularly noticeable when a significant portion of the actual water content is retained within the mortar, causing the compressive strength to be notably diminished compared to the initially mixed proportions.

Incorporating HEMC into the mortar formulation significantly enhances the water retention capabilities of the mixture.   This improvement ensures that when the mortar comes into contact with air-entrained concrete, water absorption by the highly absorptive concrete is minimized.   Consequently, the cement within the mortar can undergo more comprehensive hydration.

Simultaneously, HEMC infiltrates the surface of the air-entrained concrete, creating a new bonding surface with enhanced strength and flexibility.   This results in a higher bonding strength with the air-entrained concrete, further enhancing the overall performance of the mortar-concrete interface.
