“…Figure 11. Relationship of spacing factor and water absorption of LWA [16] The X-ray and neutron tomography study of internally cured cement paste by expanded clay demonstrated that internal curing water was the passage to at least 3 mm [18]. Micro-tomography of X-ray mortars internally cured through extended shale confirmed that internal curing water immigrates to the space of about 2 mm [4].…”

The demand for the construction of high-strength concrete in the civil engineering zone is growing, particularly in the last couple of years, due to the construction of sustainable and economic buildings with an extraordinary slim design. Concrete curing in construction is an operative manner and essential to provide that concrete structures meet future performance and durability. High-strength concrete has a low water-to-binder ratio; proper concrete curing is important to ensure its planned performance and durability. Conventionally, exterior curing applied after placing and casting concrete stays warm and moist to provide continued cement hydration. Lately, theoretically and experimentally comprehends that internal curing is an important tool to provide additional moisture in the concrete to enhance cement's hydration. Internal curing of high-strength concrete is an active technique to lessen or even remove autogenous shrinkage and effects on chemical shrinkage, dry shrinkage, etc. Most studies recently have emphasized that a reduction in high strength concrete mixtures' shrinkage is due to internal curing, and the compressive strength can increase higher in mixtures with LWA or SAP than in mixtures without this agent rising degree of hydration by providing extra water in the hydrated cement paste. However, the use of internal curing leads to improving the durability of high-strength concrete.

“…Concrete technology uses fibers to strengthen concrete structures; the major increase in compression strength has increased its importance worldwide. They use this technology and adapt it in different shapes, sizes, and colors for many building applications (Ohama, 2011;Sabnis, 2012). A feasibility study was conducted for recycling nylon fiber in concrete.…”

“…The chloride ion penetration or the use of alkali-reactive aggregates in the reinforced concrete structures were proved to be the major causes of premature corrosion of reinforcing bars and their deteriorations. Consequently the development of effective protection or repairing materials for the reinforced concrete structures is required in the construction industry (Ohama 2006;Ohama and Demura 2010). The use of ultrarapid hardening cement can make strength development rate increase.…”

This paper deals with the effects of silica fume content and polymer-binder ratio on the properties of ultrarapidhardening polymer-modified mortar using silica fume and ethylene-vinyl acetate redispersible polymer powder instead of styrenebutadiene rubber latex to shorten the hardening time. The ultrarapid-hardening polymer-modified mortar was prepared with various silica fume contents and polymer-binder ratios, and tested flexural strength, compressive strength, water absorption, carbonation depth and chloride ion penetration depth. As results, the flexural, compressive and adhesion strengths of the ultrarapid-hardening polymer-modified mortar tended to increase as increasing polymer-binder ratio, and reached the maximums at 4 % of silica fume content. The water absorption, carbonation and chloride ion penetration resistance were improved according to silica fume content and polymer-binder ratio.
