Office Feng Shui: Plants, Flowers, and Energy Flow
Arranging plants in your office is more than just a decorative choice—it's a subtle art that can influence the energy around you. When placed correctly, they can enhance your focus, bring positive energy, and even support your career growth. However, improper placement might lead to negative effects, such as blocked energy or emotional stress. From color to plant type and direction, every detail matters.
Taboos to Avoid
Avoid placing small, low-maintenance plants on your desk if you're not ready to care for them. These plants are meant to boost your vitality and energy, but if neglected, they may instead drain your strength and create an imbalance. It's essential to keep your plants healthy—water them regularly, prune when needed, and consider hiring a professional plant rental service if you’re too busy. If a plant starts to wilt or smell bad, it could affect your mood and even cause headaches or anxiety.
Plants with sharp thorns, like cacti, should be placed away from high-traffic areas. Their spiky appearance might symbolize conflict or tension, which could make interactions with colleagues or supervisors more challenging. Instead, place them in corners where they’re less visible and less likely to cause disturbance.
Orientation Matters
Position large, broad-leafed plants near the main entrance or by the toilet to help block negative energy and promote a sense of stability. They also serve as natural windbreaks. In the corners of the room, use climbing plants or tall foliage to soften sharp edges and improve the flow of energy.
If your desk faces a wall or window, consider adding vines or leafy plants to create a calming atmosphere. Avoid fake flowers—they don’t offer the same energetic benefits. A simple green plant can give your eyes a break during long work hours. If your back is against a wall, choose artwork with symbols like pine trees or peonies to add positive energy. If your desk is next to a glass wall, especially a transparent one, place thorny plants like gladiolus to protect against negative influences.
In a small office without plants, you can add patterns of red or green on the windows to bring life and energy into the space.
Color Harmony
According to Feng Shui principles, each color corresponds to a direction and element. Green represents wood (east), white represents metal (west), red represents fire (south), blue represents water (north), and yellow represents earth (center). Matching your clothing colors with the plants in your office can enhance your personal energy. For example, if you face east (wood), place green plants like monstera on your desk. If you face south (fire), choose red flowers like peonies or hibiscus. Your outfit should also align with these colors to create balance.
Choosing the Right Plants
Opt for plants with strong vitality, as they can absorb positive energy from nature. You can also rotate your office plants according to the seasons. In spring, use willow branches or peach blossoms to bring fresh energy and even symbolize new relationships. In summer, lilies or lotus flowers can purify the environment. In autumn, kumquat trees symbolize prosperity and good fortune. In winter, plum blossoms represent resilience and success.
Orchids, ganoderma, and other evergreen plants are great choices for year-round use. Additionally, carpets can act as “static flowers.†Choose patterns over solid colors to symbolize abundance and positivity. Avoid single-colored carpets, as they may limit the flow of energy in your workspace.
Polycarboxylate Superplasticizer
For example, self-consolidated concrete and slump retention beyond two hours without significant set time extension have been made possible with PCEs. I was fortunate to be on the R&D/marketing team for a major chemical admixture company that launched the first group of polycarboxylate-based admixtures in the 1990s. Like all new technologies introduced into the building industry, there has been a long learning curve which underscores the highly diverse set of materials and applications with concrete construction. This article summarizes a few key performance attributes which have been learned from both commercial concrete applications and the research laboratory. Some of the benefits provided by polycarboxylate superplasticizers have been discussed and previously published in The Concrete Producer.
The Polycarboxylate Family
The term “polycarboxylate” actually applies to a very large family of polymers, which chemists can design to impart a special performance to concrete mixtures. Subsequent to the introduction of so-called general purpose PCE superplasticizers, new PCE products have been developed especially designed to provide high early strength and different levels of slump retention, as well as provide different capabilities to manage air contents in concrete. One such class of polycarboxylates has little impact on initial slump, but because of a time-release function built into the PCE polymer, concrete slump increases generally in a predictive manner as a function of mixing time (see Figure 1). Thus, such a product can be added at various dosages to an already admixed concrete to dial in slump retention as a function of job conditions (haul time, temperature, delay before discharge, etc). Very often, a superplasticizer will be formulated with a blend of two or more PCEs to achieve a combined performance of both early strength and long slump life. Researchers will continue to actively manipulate PCE polymer structure to meet the ever changing material and construction requirements.
- Air entrainment: Essentially all polycarboxylate-based admixtures are formulated with a defoamer to control unwanted air entrainment inherent with the PCE polymer. For both air-entrained and non-air entrained concrete applications, air contents can usually be effectively managed with selection of the PCE-based superplasticizer product most compatible with job materials. Varying carbon content in fly ash can make consistent air contents challenging as the hydrophobic nature of defoamers leads to adsorption by fly ash carbon. In general, compared to polynaphthalene sulfonate polymer (PNS) based superplasticizers, PCE-based products can make air-entraining admixtures (AEA) more efficient, meaning a lower AEA can be required to achieve the same air content.
- Impact of clays: Unlike PNS superplasticizers, the PCE polymer will be readily and irreversibly adsorbed by certain clay fines that could be present in various aggregate sources. Figure 2 illustrates the impact that a clay- bearing sand, having a methylene blue value of 1.30, can have on the dosages of PNS verse PCE-based superplasticizers to achieve compatible slump. Normally, with clay-free or low-clay sands, PCEs are dosed about one-third that of PNS-based superplasticizers for comparable slump. However, when clays are present in certain sands, up to a 50% higher dosage of PCE versus PNS can be expected. Therefore, if the dosage of a PCE superplasticizer were to unexpectedly increase, checking for clay fines in the aggregate supply should be prioritized.
- Flexible dosing: Again, unlike PNS-based superplasticizers, which invariably should be added in a delayed addition mode (that is, after the cement and water have begun to mix), PCEs are relatively insensitive to the time of addition, allowing for greater flexibility in the concrete batching process.
- Incompatibility with PNS superplasticizers: Use of PCEs and PNS-based products in the same concrete mixture results in rapid loss of workability. Thus, the two technologies, PNS and PCE, should not be used in the same concrete mixture.
- Strength Synergy with calcium-based set accelerators: When PCE-based superplasticizers are used with set accelerators and corrosion inhibitors comprised of calcium salts, unexpected strength gains have been observed compared to a similar concrete mix admixed with a PNS-based product. This synergy in strength gain with PCEs was first observed in a mix containing a calcium nitrite-based corrosion inhibitor. The data summarized in Table 1 was reported by a concrete producer who had been using a combination of a lignosulfonate-based ASTM C494 type A water reducer and a Type G PNS/Lignin-based superplasticizer to manufacture prestress piles.
This remarkable strength difference, obtained by merely changing the superplasticizer type from a PNS to a polycarboxylate, was verified from a scientific study, and can be useful in reducing cement contents while still meeting strength specifications. Interestingly, the strength difference does not seem to be associated with increased heat of hydration, but rather is related to a denser microstructure produced by the combination of a calcium-based accelerating or corrosion-inhibiting admixture and polycarboxylate-based admixture.
The PCE superplasticizer replaced both the PNS/lignin and Type A water-reducing products at about one-third the dosage rate. Also, note the 50% drop in AEA dosage rate with the PCE admixed concrete to obtain the same air content.
To summarize, though the concrete industry has learned much about harnessing the versatility and understanding the limitations of PCE-based superplasticizers, chemists, working with concrete technologists, will continue to modify the polymer structure to achieve new capabilities for the production, placement and service life of concrete mixtures.
