  An exceptional resin-based hydraulic binder containing distinctive chemical ingredients which, when mixed proportionately with graded aggregates and water hardens completely within the first 24 hours following the installation regardless of t
he thickness of the screed; promoting a shrinkage-free finished concrete topping with high mechanical strength even in the most unfavorable conditions.  When it is properly used, the residual moisture content after 24 hours is less than 2.5%.  MAPECEM is 
used like any ordinary PORTLAND cement mixed in a normal fashion with sand and aggregates properly graded and sized in relation to the dried thickness of the finished topping.
