“…The following results from tests for the flow cone, compressive strength, and flexural strength of fresh and hard grout are displayed: 3 and Figure 8 show the flow time that was test used to evaluate the performance of the grout. According to previous studies, a flow cone test is conducted for several types of grouts to achieve a sufficient fluidity of (11-16) seconds [5,12] for appropriate grout injection into the SFP surface mixture. The presence of a superplasticizer has a substantial impact on the workability of cementitious slurries, regardless of the W/B ratio.…”

“…The use of cement grouts in environmental areas for securing harmful and reduced radioactive wastes has grown. According to published research, grout can be used to solidify and stabilize burial waste ditches [5,6].

Cement-based grouts are described as a liquid mixture with higher flowability that contains cement, additives, water, and a superplasticizer. Cement-based grouts can be utilized to fill minor voids and gaps in addition to repairing cracks in earthen structures to restore structural continuity. In most cases, structural grouting is used in conjunction with other strengthening methods like adding tie-rods or reinforcing meshes. Grout is usually used with semi-flexible pavement (SFP). SFP is a new pavement technology comprised of open-graded asphalt concrete with a high air void content that is filled by injecting special grouting materials. The goal of this research is to figure out what happens to the mechanical properties of grout when a proposed by-product is used as a supplement to cementitious materials. The specified grouts were made from cement, water, ceramic waste powder (CWP), and superplasticizer (SP). Scanning electron microscopy (SEM) and energy-dispersive x-ray (EDX) analysis were used to characterize the physical and chemical properties of the waste material after it had been crushed and finely ground. The pozzolanic behaviour of the material was evaluated by substituting ceramic waste for Portland cement at varying percentages (from 15% to 50%), and the modified grout was characterized through a variety of tests that included flow cone testing, as well as compression and flexural strength tests Based on the results of these tests, the best amount of CWP to use as a replacement for cement in terms of its mechanical properties is 20%.

“…Since sealing joints and cracks is one of the main applications of grouts, the results obtained from DPT are considered interesting for the determination of the compression strength of the mixture in this situation. With regard to obtaining flexural strength, the three-point flexural test is the proposed methodology, where researchers [12,31,[47][48][49] and standards [30,34,45,50] employ similar shapes and sizes of specimens.…”

Ultrafine hydraulic binder grout injection is a technique utilised for repairing masonry, either to connect sections, seal joints, or fill voids due to its great capacity for penetration and higher mechanical strength than lime grout. In this research, the mechanical properties of ultrafine hydraulic cement grout are analysed considering the influence of the mould material for preparing the specimens and their geometry characteristics in the context of the specifications set out in several international standards. The test campaign to ascertain compressive and flexural strength in different circumstances is supplemented with a physical and chemical characterisation of both binder and fresh and hardened grout. Significant differences in mechanical properties between specimens prepared with absorbent or non-absorbent-water material are found due to the influence of drying shrinkage and decanting binder during the curing process. Furthermore, the slenderness of specimens is presented as an important factor in determining the compressive strength of mixtures.

“…It can combine the best characteristics of rigid and flexible pavements. Grouted macadam, also known as semiflexible pavement surfacing, is described as having an impermeable surface, a long operational life, great rutting resistance, and high durability [7]. A semi-flexible material that is typically utilized as the top course of specialized pavements (industrial floors, distribution centers, harbors, airport pavements).…”

In last years, a new type of pavement has gained popularity, this type is called Semi-Flexible Pavement (SFP). It consists of porous asphalt with high air voids between (25-35) % filled with cementitious grout materials. This type of pavement substance offers substantial advantages over both common types of pavements (concrete and flexible) such as good resistance to rutting and durability. SFP is considered an alternative pavement to exceed the drawbacks that occur for both flexible and concrete pavements. SFP has good features against permanent deformation, oil spillage, and fatigue resistance. Previous studies have shown that it can be used in a variety of applications such as highways, motorways, bridge deck pavement, tunnels, industrial areas with industrial equipment traffic, airport aprons, and stations. The goal of this research is to identify and compile the most significant research papers using the Web of Science (WOS), analyze the data using the VOS viewer software, as well as learn which countries and institutions had published the most articles relating to the subject of cementitious grout material as it relates to semi-flexible. It was also done to learn more about the authors and their collaboration. In addition to knowing the keywords that will aid researchers in their research on this topic, using these studies to better understand the elements that affect how well semi-flexible mixtures and grouts perform such as porous asphalt Mixture gradation and grout material components.
