Nowadays, floors with concrete layers are generally being used in most residential building objects. They are used, among others, in residential and public buildings, warehouses, production buildings, and one and multilevel car parks. A concrete floor consists of an overlay that is usually made of cement mortar and substrate (figure1).
The results show that cement content of mortar has no significant influence apparent that “adhesion” between the brick and the mortar does serve a stmctural.
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together.
Use of polymers as partial replacement for portland cement in cement mortar and concrete can diminish several drawbacks of these composites such as low tensile strength and strain capacity, high permeability and low adhesion. Main reasons for the use of polymers are to improve damage tolerance, adhesion, and resistance to water permeation.

In this study, cement mortars were modified with a commercial polymer admixture. The aim of this study is to investigate the influence of the polymer content on the mechanical and adhesion properties of the mortars and to relate these properties with mortars’ microstructure.
Adhesion, we can take the force or energy required to separate the two bodies. We studied this problem in the context of repairing mortars laid down on a concrete support; we focused our research on the behaviour of a cementitious slurry applied on two types of concrete support, characterised by their surface preparation (sandblasted.
Various ratio of cement mortar in brickwork at various thickness of mortar between brick layer. 5% of fibre with 1:3, 1:4, 1:6, 1:8, 1:10 ratio of cement mortar for the various thickness of cement mortar between brick layer of 8mm, 10mm,.
Cement as unprocessed mortar, and without several of its initial properties, can be found deep in the past. There is a reasonable assessment that the connecting material for the processed stones in the egyptian pyramids was a mortar type material, with similar properties (regarding stone connection and adhesion) to cement.
The adhesion performance of hmp to cement mortars after each round of heat treatment was recorded as the bonding strength readings of the machine.

The main method used to determine adhesion strength is the pull-off test. The pull-off test is based on the concept that the tensile stress necessary to pull out a metallic disc, with a coat of mortar, from its substrate, is empirically related to the mortars tensile adhesion strength.

Concrete properties are affected by the cement and the mechanical as well as some durability properties of cements are determined through cement mortars. Applications of ultrasound on determining the properties of cement mortars are quite limited.
Adhesion strength was calculated with pullout testing apparatus designed by the author. Results indicate that recycled abs had a lower adhesive strength than the acrylic latex emulsion and the base mortar, but did increase in adhesive strength when mixed with maleic-anhydride.
0 cured for 3 months laid on a water-soaked brick and a roman cement historic substrate a clear correlation between adhesion and curing time, equivalent to the degree of hydration, is observed.
Water is often added to concrete placing for easy workability and finishability in construction site. The additional mixing water can help easy mixing and workability but causes increased porosity, which yields degradation of durability and structural performances. 45 of w/c (water to cement) ratio are prepared for control case and durability.
The interaction between masonry units and mortar is a crucial factor for the quality of a wall. The most important factor is the adhesion between bricks and mortar in order to construct a masonry.
