Run coarse grit pads at lower speeds to prevent the teeth from skipping over the concrete's surface. 3. Move Methodically Over the Concrete. Move over the concrete methodically so you don't miss spots or spend too much time in one area. The speed at which you move across the floor may take some practice.

Their efects on hardened and fresh properties were investigated by cement. replacement of 15, 30 and 45 m%. The waste perlite powders demonstrated higher reactivity, while the recycled concrete powder. would act mainly as a filler material. When using recycled concrete and waste perlite powders, an adverse efect was identified on the.
